Edit the Core Lightning CLN RTL config file

I get this error when trying to do it through CLN RTL.

Also, I tried editing RTL-config.json here… umbrel/app-data/core-lightning-rtl/data/rtl via SSH.

BUT I ended up wiping my node!, so don’t do that! Bottom line, I just want to be able to change my alias and also, enable bolt12 offers and I need to edit the config file.
