Heard about this on Linux Unplugged a few weeks back. Haven’t had a chance to test it out yet, but it looks pretty cool.

I used it when it first came out. Fully FOSS. Great app. 6mo in, enshitification. Try out CCLauncher. It’s a fork of the same project but clean and fully FOSS. https://f-droid.org/packages/app.cclauncher/
