Scenario:
Following the migration from WCFM, WC Vendors, and YITH Multivendor plugins, a new feature has been introduced where users can activate the Dokan dashboard. This feature serves to deactivate all previously migrated plugins. However, despite deactivating these plugins, the custom pages created by them are not automatically removed. This results in a cluttered experience for users who wish to utilize the Dokan plugin. To enhance user experience, it is essential that all pages generated by the migrated plugins be deleted when activating the Dokan dashboard.
