How to keep your current location icon in the center of the screen?

I have an InReach Mini 2 and use the Explore App on my iPhone 13 while riding my motorcycle on fire roads following GPX tracks.

I would like to keep the current location icon in the center of the Garmin Explore App on my phone.  Sometimes it keeps the current location icon in the center of my phone screen, and other times is does not.  

How can I keep the current location icon in the center of the Garmin Explore App on my iPhone 13?

Thank you for your help!
