How to use PulseEffects in Google Meet with Noise Cancellation/Reduction?

I have been suggested to use pulse effect in my previous topic and I tried to work around it but still didn’t get it
pulse effect does take my headphone as input and output but I don’t know how do i use it in google meet?
I am giving couple of images of google meet speaker and microphone(Using Boat Rockez 510 with inbuilt mic) by the way I am using PulseAudio

Without pulse effect how I use to use my headphone in google meet:

after I tried to use pulse effect I get these options in speakers:

But I didn’t get any options in microphone:

Is anyone here who can guide me how to pulse effect in google meet,zoom,discord
