How can I remove the red and a green dot too from upper right corner of iPhone 11?

I need help in solving this problem. Everytime I make a call or someone calls me, that red dot comes on. I think that all my calls are being recorded, and this is a problem. When I make payments using my phone and have to give personal info to the payer, this red dot is obviously recording everything I say and stealing my bank acct numbers. Pls tell me how to get rid of this once and for all. I cannot find any apps using the microphone and it’s always turned off. What else can it be, and where do I turn it off or delete it if need be? Thank you for your kind support.
