I am far away from my computer right now and i want to join using a mobile java launcher to join.

Does "mobile java launchers" imply a full on Minecraft Java Edition game, or just a chat client? I'm fairly certain chat clients are allowed, not sure about stuff like Pojavlauncher (I think it was called that?).

Pojav is dated, look up MojoLauncher, I used them in past, not sure about if we can still use them now.

It's going to be a good couple of weeks until you're whitelisted so hopefully you'll be back at your computer by then!

Pojav and Mojo are literally just third party apps that run java minecraft on your mobile. There's no real harm in using them, only clients that enable hacks or other exploitive features aren't allowed.
