Windows 10 Specific Mirroring to TV

Hi guys I have a quick question.

So I've been mirroring my Windows 10 PC to my TV by using an HDMI cable. That's the best way for me. But I noticed that I can't use my PC to do something else while having a specific tab be mirrored to my TV.

I know there's a way to do this I just don't know how,

I guess what I'm asking is, how do I mirror a specific application/tab PC screen onto my TV while using any other application or tab to do other things without having that be mirrored too?

Thanks!
