Appointments + hook/action Service Provider Removed


I am looking for a hook/action that I can use run my function after an Appointments + Service Provider is deleted from Appointments +. Unlike when services are deleted from Appointments + and the action hook
do_action('app-services-before_save'); //line 5561 Appointments + version 1.4.6
is run. Is there a similar do_action('app-service-provider-before_save')?

Otherwise any suggestion on how I can hook onto a service provider delete event from Appointments +?

Thank you,
