Minecraft Trial allows you to connect to your Microsoft account and also to The Hive, the featured server

This is a bug reported by one user on a Discord server I am on. According to that person, "When I start Minecraft Trial and press "Play" and then "Servers", I get this thing, and when I close it, I can fiddle with the server field for a split second. If I use that split second to press add to server, it takes me to the sign-in screen, and if I sign in from that screen, I can sign in."
"And from that add server screen, even if it's a trial version, I can get into Hive and so on," he said.

I'm using Deepl to translate from Japanese to English, so the text may be wrong.
