@K.R ,
This is because Elgato cam is not a certified Teams camera device. Microsoft is working with device partners to bring more new Teams certified devices to market. You could refer to this link to know more certified devices.
Besides, the highest resolution for Teams media quality is 1080p now. You could vote in this UserVoice link and add your comments.
Microsoft will always focus on customer’s feedback and experience. Some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service.
Your time, understanding and cooperation will be highly appreciated.
