I used this code to addextra tab, but it seems to be that the tab will be shown if the user is login, how can i make it public even non-register users can see it? Thankyou

//add maintab 
function profile_new_nav_item() {

    global $bp;

    bp_core_new_nav_item(
    array(
        'name'                => 'Store',
        'slug'                => 'store_tab',
        'default_subnav_slug' => 'store_tab', // We add this submenu item below 
        'screen_function'     => 'view_manage_tab_main'
    )
    );
}

add_action( 'bp_setup_nav', 'profile_new_nav_item', 10 );

function view_manage_tab_main() {
    add_action( 'bp_template_content', 'bp_template_content_main_function' );
    bp_core_load_template( 'template_content' );
}

function bp_template_content_main_function() {
    if ( ! is_user_logged_in() ) {
        wp_login_form( array( 'echo' => true ) );
    }
}

//add sub tab01
function profile_new_subnav_item() {
    global $bp;

    bp_core_new_subnav_item( array(
        'name'            => 'Pstore ',
        'slug'            => 'pstore_tab',
        'parent_url'      => $bp->displayed_user->domain . $bp->bp_nav[ 'store_tab' ][ 'slug' ] . '/',
        'parent_slug'     => $bp->bp_nav[ 'store_tab' ][ 'slug' ],
        'position'        => 10,
        'screen_function' => 'view_manage_sub_tab_main'
    ) );
}
add_action( 'bp_setup_nav', 'profile_new_subnav_item', 10 );

function view_manage_sub_tab_main() {
    add_action( 'bp_template_content', 'bp_store' );
    bp_core_load_template( 'template_content' );
}

function bp_store() {
    if ( is_user_logged_in() ) {
        //Add shortcode to display content in sub tab
		
    } else {
        wp_login_form( array( 'echo' => true ) );
    }
}
