How do I add MS Teams to meetings, not default Skype?

Question

I hold a licence for Microsoft 365 Family.

I want to use MS Teams for video calls, but the default system is Skype. How can I change from Skype to MS Teams so that I can define the invite is a MS Teams invite directly in outlook?

i.e. I generate the MS Teams link directly in Outlook

I've followed the advice existing on here so far and it points to 'Options' which no longer appears to be available, and 'Add-Ins' which no longer appears as a drop down, nor as a selectable option in the calendar. Finding 'Add-Ins' and switching default from Skype to Teams would likely resolve this... if I could find it!

Thank you
