Invite Module | Delete invite

User Story

As a user, you should have the ability to delete your invitation using a valid invite ID and user ID. The first step is to check whether the invite ID is present in the database. If it is, the system will verify whether the user ID assigned matches the given user ID. If the invite ID is not valid, an error message stating "Invalid invite ID" will be displayed. Likewise, if the user ID is not valid, an error message saying "Invalid user ID" will be shown. Only if both the invite ID and user ID are valid will the invitation be deleted from the database.
