idea recommendation to convert my old unused kenwood headphones into aprs cable

It still works but since the headphone is of poor quality I will get rid of that part and solder a 3.5mm aux. The real problem is how to remove the mini microphone. I don't have a heat gun, I only have solder and a soldering gun. Also, even if I remove this mini microphone, is it ok to solder the mic input? I am open to all ideas. Thanks in advance

Basically what I want is to make the connections like this (although it is different from the circuit sketch.) resistors and non-polar capacitor circuit may be different. The only thing I want is for my radio not to be stuck in tx. Other than that, I will connect the wires like that blueprint

I wanted to do this because when I make these types of connections directly, my radio gets stuck in tx. with this cable, I hope this won't happen anymore. everyone can tell me about buying a classic aprs cable, and all are right. But for me it seems impossible 😅 I don't want to pay product fee + shipping + I do not want to be taxed almost 3 times higher than the product fee and shipping fee.
