In that case, you can just do this:

<?php if ( bp_has_activities( bp_ajax_querystring( 'activity' ) ) ) : ?>
    <?php while ( bp_activities() ) : bp_the_activity(); ?>
 
        <?php locate_template( array( 'activity/entry.php' ), true, false ); ?>
 
    <?php endwhile; ?>
<?php endif; ?>

Unless you filter this, it’ll show everything.
