Your one calendar feed, wherever you subscribe from

You'll see a "Subscribe to your matches" button in a few different places — on a season's Schedule tab, on the "My matches" page, and in your Account settings. They're not three different feeds. It's the same one, every time.

That single feed already covers every match you're scheduled for, across every club and season you're part of — subscribing from any one of those places gives you the same link and the same content. Set it up once, from wherever's convenient, and you're covered everywhere; there's no need to separately subscribe again when a new season starts or you join another club.

A club can also set up its own club-wide feed, covering every season and every player in that club — that's a different thing, configured by an admin, not you, and meant for sharing a full overview with someone who wants to see the whole club rather than just your own matches.
