Twitch show viewer numbers for the streamer?

I only had 1 monitor, I managed to display the chat, I wanted to ask if this was also possible for the number of viewers

I recommend the Twitch app. There you can take the chat in parallel, view the number of viewers or activities such as followers, subs, etc.

In general, I do not recommend to fixate on the number of spectators:-)

But I don't want to have to constantly look at my cell phone.

The same goes for a tablet. Or maybe a second monitor.
