Calls service / cloudflare TURN in nextcloud?

Currently there seem to be no way to seek support for the beta calls service via the support categories. there is no calls service in the drop down list.

Would like to get some help if there is any way to use the TURN service in Nextcloud.

Currently nextcloud uses SECRETS for the turn auth Overview - Nextcloud Talk API documentation while the TURN service in cloudflare uses user/password (id/api-key)
