My lightning to 3.5mm adapter is not working for calls

The Issue I am facing is that I have original Baseus Lightning to 3.5mm converter and when i plug in headphones or earbuds, it works just fine. But as soon as my mic opens, I stop hearing audio from headset and audio shifts to phone’s external speaker.

This happens allot while playing PuBg, i can play it normally and hear other peoples voices and game audio from headphones as long as my mic is turned off. If i turn my mic on, then all voices shift to external speaker and i hear nothing.

any fix will help allot. I have tried various ear buds which company claims to be compatible with iphone (so there is no issue there) .
