sound – Microphone showing in pulse audio, but (discord, gmeet,nd everywhere) can’t hear it!

I am using Ubuntu 20.04. In pulse audio, When My earphone is inserted
I can hear other’s audio, but other’s can’t hear me

In PulseAudio, in Input devices, I can see
Internal Microphone(unplugged)
Microphone(plugged in)

In the microphone, my audio is not showing
in internal microphone, my audio is showing
I tried in pulse audio, I set my right music to 0 and set to fallback and yet no one can hear me

Thanks for helping
