If you wanna join a meeting from another company and you dont have teams licence, you can only use browser or mobile app (not sure if this was changed later or not, because by winter every company I manage had bought ms 365 business. Though teams licence is still an extra item in MS365 admin so I'd assume it hasn't changed)
