So what code/link for the meeting did you get?
https://meet.skype.com/room-name
https://join.skype.com/code
— those are for Skype. You need to open it in Skype. Click the camera icon -> Meet Now -> Join a meeting, and in the newly opened window, enter the link or code.
If it’s a link like https://teams.microsoft.com/l/meetup-join/...
then it’s a Teams meeting. If it’s not a problem, ask the person organizing the meeting to create it in Teams instead, since Skype won’t last much longer anyway, as others have already mentioned above.
