Yes, deactivate, delete and install the new version is how you update. WordPress actually doesn’t have a manual way to upgrade a plugin or theme.

I see, the license key, you will not have one, sorry about the goose chase. You will actually be able to manually update for as long as you wish. The only way to enable the in-admin updates is if I generate a license key for you and if I do that, the license key have to be renewed annually for continued updates, even manually. I can do that if you wish, just let me know.
