prevent media app activation/display from lock screen on iPhone12

I have a problem that when my iphone 12 is off and in my pocket the controls for media apps like audible or voice dream reader (whichever I've used most recently) are displayed on my lock screen, and the players keep activating when I put my hand in my pocket, walk, etc. I want to prevent them from being activated from or even showing up on the lock screen, but I can't find where in settings I can prevent this from happening. I have searched through the support files and can't find the instructions on how to do this. Can someone please help?! It is very frustrating because every time I try to restart one of my books on tape it has advanced to a new location because it has begun playing in my pocket. Thank you
