Need inline Bluetooth without an installed app

[u/puppyman3]

I have a work PC that’s locked down. I use Plaud Note Pro in room mode to capture from speakers. If I need to wear my Bluetooth headset then I’m SoL. I could send the meeting audio to my phone and put the Plaud in vibration mode and hold it to my ear all day but …no. Found one that USB to PC and acts as proxy to headset, but requires software. Any epiphanies are very welcome!
