filter backend submission

I purchased this plugin which basically allows users to create ticket linked to woo commerce products https://codecanyon.net/item/woocommerce-support-ticket-system/17930050. My problem is that in the dashboard all shop managers can see all tickets and not their own as it doesn’t automatically assign based on post author. I can see the post author id in the ticket url but I have no way of only showing each other their tickets.
Is there a simple function I can add or a plugin you can recommend?
thx
