Mumble instead of discord

I'm trying to get my group to play games with mumble instead of discord.

I see lot of interest and ease of installation around matrix and jitsi, however mumble seems not talked about much.

I am looking for a guide of sort to setup mumble the easy way, i don't want to get new domain and vps and i don't want to open ports in my home router.

I've tailscale/headscale running off site with tunnel to home And i also have matrix server running with traefik.

If anyone have experience in the similar scenario i would like to know
