->tenant(Team::class); if you only have a simple one-to-many tenancy which I do have, but I fail to understand how I would use the ready-made solution to Laravel Spark since it uses ->tenantBillingProvider() (https://filamentphp.com/docs/3.x/panels/tenancy#using-laravel-spark) if I don't have the ->tenant() in the first place.Account which has many Users and that's it.
