philips oled804 mic+cam for google due

[Angelo Mantellini]

Hi,
I'm trying to use google duo on my tv, philips oled804.
I'm using a logitech cam without problems, but the problem is the microphone.
I'm reading that with other TVs, people are using the remote michrophone, but I don't know if my tv is enalbed to use it.
I want to know if I can use an usb mic (which one?) or I cant' use google duo on my tv.
thank you very much

Angelo
