Notification sounds when wearing headphones

I have a brand new pixel 8 (not pro) and im trying to get it to give notification sounds when i have the phone connected to my bose headphones but am listening to something from my computer. If im not listening to something on a secondary advice, the pixel does send notification sounds to my headphones. I just need to be able to hear notification sounds from texts, because currently it just does a little vibration, and i keep missing texts. Apologies if this has been asked before, or if im unclear - i'm at my wit's end here, any help would be appreciated.
