When I am changing the keybindings in consoleport and saving the change just won’t appl. Even after log out and log in.

It quite easy. Youtube has a lot tutorials. In short: first download battlenet on steam deck and install it. Then add battlenet in steam (add non-steam game). Secondly start battlenet trough steam and log in. Install wow. After that install curse forge for addons. Obviosly you have to install the addon ConsolePort. Also nice to have is VoiceOver for quests. Have fun.

you can sell it to me. In my country are no steam decks available.
