Can't play minecraft normal offline using minecraft launcher in linux

Hello,

I noticed that unlike Windows, when we have no internet connection and play to Minecraft in Linux, the game is in Demo Mode, and the launcher's button was not "Play Demo" or something similar, but was "Play offline, but the launcher just say that can't connect to Minecraft services and can't verify "my products", like in Windows, but launch minecraft as Demo Mode

(In Java edition i don't have test in bedrock edition)
