Add the ability to edit the username trough QRookie, the action itself is very simple, I did it on bash here: https://github.com/XargonWan/metaquest-username-changer

@XargonWan, can u reopen this issue on this repo: https://github.com/victorwads/QRookieNode

I think the follow up an fixes will be happening there. with the Node version that will be available on more platforms, like Android (Termux + Browser), Windows, Linux, MacOs and maybe more.
