LinuxServer addon> Letsencrypt is dead, long live SWAG --> how to add EXTRA_DOMAINS ?

Hello,

would you mind updating LinuxServer.io docker addons and general docker info - Add-on Support - LibreELEC Forum as docker-letsencrypt/README.md at master · linuxserver/docker-letsencrypt (github.com)

THIS IMAGE HAS BEEN DEPRECATED AND THE PROJECT IS MOVED TO A NEW REPO

which is linuxserver/docker-swag: ...

Moreover, how do I add

docker run -d \  
....
 -e EXTRA_DOMAINS= `#optional` \
....

to /storage/.kodi/userdata/addon_data/docker.linuxserver.swag/settings.xml?

Is it <setting id="E_extrad">wildcard</setting>?
