A. Check if there are any settings within the app that allow you to assign approver roles. Navigate to the settings or user management section and look for options related to permissions or roles. If available, assign the necessary roles to users who need approver access.

B. If the app does not support approver functions, consider using a workaround by creating a shared document (like Google Docs or Sheets) where users can submit requests for approval. This can serve as a temporary solution until the app is updated.
