How to stop sharing a device?

I share a device with more than 20 users but I want to stop sharing it with any of them without having to delete their email in the application, thank you

in the eWeLink app, go to Profile - Manage Sharing - Device sharing
there you can remove them.

Thanks for the response, but the only options the app allows is to delete the email (user) or share temporarily. It has the CONTROL DEVICE option but it is disabled (gray).
