@modemlooper The only problem is i am updating the content with the Post ID and thumbnail of the post for activity prior to submitting it, is there any other way of doing is ?

add_action('bp_activity_before_save', 'rewards_activity_content', 3);

add_action('publish_rewards', 'groups_rewards_activity',4,1);

/* Filter for content for post type reward before saved to database */
function rewards_activity_content($activity){

    global $post;
    global $bp;

    if ($post->post_type == 'rewards') {

        $activity_id = (int) $activity->id;
        $post_id = (int) $activity->secondary_item_id;
        $user_id = (int) $activity->user_id;
        

        $post_type = get_post_type( $post_id );
        $thumbnail = get_the_post_thumbnail($post_id);
        $post_permalink = get_permalink($post_id);
        $title = get_the_title($post_id);

  

        $activity_content  = "<div class='post-id'>The post ID : {$post_id}</div>\n";
        $activity_content .= "<div class='thumbnail'>{$thumbnail}</div>\n";
        $activity->content = $activity_content;

        $group_id = (int) BP_Groups_Group::group_exists($field_group[0]);  //working :)

        
    
        $bp->groups->current_group = groups_get_group( array( 'group_id' => $group_id ) );

        $groups_activity_action  = sprintf( __( '%1$s posted a reward %2$s in the group %3$s', 'buddypress'), bp_core_get_userlink( $user_id ),'<a href="' . $post_permalink . '">' . $post->post_title . '</a>' ,'<a href="' . bp_get_group_permalink( $bp->groups->current_group ) . '">' . esc_attr( $bp->groups->current_group->name ) . '</a>' );

        $groups_args = array(
            'action'            => apply_filters( 'groups_activity_new_update_action',  $groups_activity_action  ),
            'content'           => apply_filters( 'groups_activity_new_update_content', $activity_content ),
            'component'         => 'groups',
            'type'              => 'activity_update',
            'type'              => 'new_forum_post',
            'primary_link'      => $post_permalink,
            'secondary_item_id' => $post_id,
            'item_id'           => $group_id,
            'user_id'           => $user_id,
        ); //all of groups_args array value is being populated

        //do_action( 'bp_activity_add', $groups_args ); //not working
        do_action( 'groups_rewards_activity', $groups_args );

    }

    return $activity; 
}

function groups_rewards_activity($groups_args){

   $id = bp_activity_add($groups_args);

   return $id;

function rewards_activity_content($activity){

    global $post;

    if ($post->post_type == 'rewards') {

        $activity_id = (int) $activity->id;
        $post_id = (int) $activity->secondary_item_id;
        $user_id = (int) $activity->user_id;
      
        $post_type = get_post_type( $post_id );
        $thumbnail = get_the_post_thumbnail($post_id);
        $post_permalink = get_permalink($post_id);

        
        $activity_content  = "<div class='post-id'>The post ID : {$post_id}</div>\n";
        $activity_content = "<div class='thumbnail'>{$thumbnail}</div>\n";
        $activity->content = $activity_content;
        $activity->action = sprintf(__('%1$s posted a new reward: %2$s', 'buddypress'), bp_core_get_userlink((int) $post->post_author), '<a href="' . $post_permalink . '">' . $post->post_title . '</a>');

    }
    return $activity;
