need help with microphone and iPhone

So because of everything going on nowadays, I’ve taken up online activities. Unfortunately with my vocal disability along with very little vision it was quite frustrating to try and get people to hear me.

So I went ahead and ordered apples Lightning to 3.55 mm adaptor along with a clip on microphone on Amazon. It all arrived a couple days ago and I was so excited to get all set up and running. My mom helped read all of the instructions and I followed everything exactly, here is what I did.

Put the microphone onto my shirt
Connected the microphone to the adapter that came with the box in order to fit into the phones dongle
Pluged the headphone jack into the dongle
Plug the dongle into the phone

But here’s the problem… As soon as I plugged the dongle in, The audio cut off. So I thought OK no big deal and unplugged the dongle. I grab my Bluetooth headphones and turn them on and make sure voiceover was working and I could hear everything going on on my phone. I then connected the dongle back onto my phone and… All of the audio stopped again.

Am I doing something wrong? is there any possible way to get around this? Please any help would be greatly appreciated.
