Problem with celia mining app

I used to mine Celia coins and mined a large number of them, but unfortunately, after deleting the app, I lost it. Now that the cryptocurrency migration phase has begun, I searched for the old app and found that you can also buy a Celia wallet. Unfortunately, there's no technical support I can contact except through their Twitter page, and I sent a message but haven't received a reply yet. Does anyone have a solution to this problem?
