No back button or close botton on tracking popup

Hello there,

I’m wondering how the customers can close the tracking details popup after opening, specially on mobile devices. On computer devices it can be done by clicking anywhere outside the popup.
But for Mobile devices It can be done by only using device nav back arrow icons on bottom, but on doing so it also backwards the entire view-orders page. Which is not a smooth behavior I think.

All I want is a close icon on the top after opening tracking details.

Regards
