If OAuth success what would be expected response body?

🤔 didn't get sorry

promises here refer to javascript promise ?

What information you want to get from the promise?

Yes

pretty much I want user to be automatically redirected back ( nothing else I guess), but I wonder what is the use case of these then...

as rn user see the pop-up and then they have to click Ok or Cancel

You have popup? No redirect?

nope not automatically

one min let me show

Okay

so, this what pop-up gets , but after clicking open does work

Oh you talked about this
mb
try to change your browser to chrome and lmk

ah, so it's browser base thing

then no worries

that config seems to be already there...

Ok so found the reason why this pop is coming, it is because there are two apps with same package name, as I had dev version and release version so firefox was not sure which screen to redirect.

Cool

Ah no no may be my assumption is wrong 😅 this still happened ( just before posting last message I tested on Chrome) but when switched to Firebase it does still shows the message

I think because this is Firfox and not the System one it will always happen

can be likely cases to me it seems

This is indeed a firefox issue as @Binyamin stated.
I cleared the defaults in Firefox, and it opened the link in chrome, which redirected me back successfully
