When opening the in-game chat and then the on-screen keyboard from Steam Deck, the on-screen keyboard is on top of the chat so I can't see what I'm typing.

Describe the solution you'd like
Either to have the keyboard open at the top instead, or make the chat offset from the bottom so it's above the virtual on-screen keyboard when active.

Another option if integration is too difficult: to allow opening the chat but with a configurable offset. And then adding a preset/suggestion of 357 pixels, as that seems to be the height of the Steam Deck virtual keyboard.

Looking at the steamworks4j that you mentioned in a different issue (#77 (comment)), then it seems to have a method for opening text inputs: https://github.com/code-disaster/steamworks4j/blob/1.9.0/java-wrapper/src/main/java/com/codedisaster/steamworks/SteamUtils.java#L115-L120
Would be useful when specifying the input fields like signs and anvils as well. Found the function on the Steamworks docs as well: https://partner.steamgames.com/doc/api/ISteamUtils#ShowFloatingGamepadTextInput

Describe alternatives you've considered
It should allegedly appear from the top when the mouse cursor is at the bottom, but that doesn't work for me in Minecraft (ref: https://www.reddit.com/r/SteamDeck/comments/uni3tb/comment/i887zx1/?utm_source=reddit&utm_medium=web2x&context=3). Works like that in Firefox though, where it also seems to be dependent on where the focused input field is and not only where the cursor is.

Additional context
Device: Steam Deck
Modpack: Fabulously optimized
Minecraft version: 1.19.2

Screenshot after pressing Right D-pad to open chat, then Steam + X to open keyboard (even when having mouse cursor at the bottom):

I added an option to move the chat input box to the top of the screen in some update after you reported this :)
