Add filter not calling function on push

I am new to using Object Sync for Salesforce and I am trying to trace down why an add_filter is not being executed on an existing site. I have successfully traced the through is_push_allowed.

As of yet, I have not been able to make the filter call its assigned function.

Here is what I have:

$push_allowed = apply_filters( $this->option_prefix . 'push_object_allowed', $push_allowed, $object_type, $object, $sf_sync_trigger, $mapping );
 
add_filter( 'object_sync_for_salesforce_push_object_allowed', [$this, 'check_user_add_action_sched'], 10, 5 );

public function check_user_add_action_sched( $push_allowed, $object_type, $object, $sf_sync_trigger, $mapping )
