Multitasking overheats my pixel 9

I got a Pixel 9 last month and everything seems great except the overheating when I'm using YouTube and some other apps simultaneously. I think it's only with streaming something and using other apps, but even then, I don't think it should heat up in such cases, right?

I come from a Oneplus 9 so battery was terrible but didn't face this kinda heating issue before.
