Hello
This is a feature only available to accounts associated with a business tier license. You are on a personal Microsoft account, so this will not work. You need to create your meeting in Teams calendar tab instead.
However, if you use New Teams, the calendar tab there allows you to launch an item and it will include the Teams meeting toggle. But you will not see it since you are using a third party email address as your Microsoft account alias. For the toggle to show up, you need to assign your Microsoft account an outlook.com alias instead, and sign in using this outlook,com alias in new Teams.
To give your account an outlook.com alias, go to https://account.live.com
Go to Your Info > Sign in preference, Add an alias.
Create new: this will allow you to use the native domain outlook.com to create a new alias.
Once added, make this new alias your primary alias, then you can delete the other email as alias, gmail can stay as secondary.
