Wireless Handsfree Streaming Camera???

I want to wear a camera to live stream various activities at my store. I recently bought a GoPro Hero Black 12, but I'm starting to wonder if I went wrong.

The camera and head/chest strap are fine, but I want to stream to TikTok, YouTube, etc with the ability to add other cameras depending on the activity. Kinda like a Picture in Picture thing.

Before I start researching the technical aspects of all that I want to get opinions on the best camera options for a beginner (I don't want to spend thousands on the setup).

Thanks
