Set different Posts per Page

WP 6.0.2, TEC 6.0.0.1

I would like to set a different Posts per Page for TEC than is set in Settings->Reading. That is set to 6, and I’d like the calendar (list view) to show at least 20.

I tried following the directions in the TEC knowledgebase, adding the filter

add_filter( 'tribe_events_views_v2_view_latest-past_repository_args', function( $args, $context, $view ) {
    $args['posts_per_page'] = 20; // Or whatever...         
    return $args;     
} ); 

but it’s not working. I cleared my site cache and browser cache, but still no change.

Is there another way to do this or am I missing something?
