I have installed MirrorGo (Stream & Recorder) app from playstore to try and uninstalled over privacy concerns in my android 10. Everything looks fine but recently I discovered it still left some traces in the device. When I checked the virtual keyboards in Language & input settings, I found MirrorGo keyboard is still available. I tried checking list of all apps on the mobile and couldn't find anything related to that. How do I remove that from my device?

Device: Pixel 3;
Android Version: 10 / Android Q;
Device status: Unrooted;
