How do I get it working on Twitch and Bluesky?

subject

It isn’t detecting the username and password that I entered for both of those sites.

I hope they get supported eventually (along with another one I found, which is Fansly).

Kee is working just fine on those two sites for me so it’s weird that it’s not working for you.
I just have a regular entry in KeePass for Twitch with the URL https://twitch.tv/ and Kee fills in my name/password when I go to Twitch and click the Log In button.
The same with BlueSky, I just have a regular entry in KeePass with the URL https://bsky.app/ and Kee fills in my name/password when I goto BlueSky and go to the login screen.
