You can try adding terms like “accessibility device” or similar to your web search terms. Ditto seems like a good option if you can source it. It looks discontinued.

Your next option may be to use the screenless fitness trackers and deny permission to fitness data if thats possible on your phone. Razer nabu possibly?

Maybe try searching for remote control couples toys, some of those apps should have this functionality though it may or my not be an acceptable solution at/for work
