How to open this door?
 

I have a walkout basement door that is a prefab unit that has a door on one
side and a glass panel/non-opneing door on the other side. I need to bring
in a new shower kit and would like to temporarily remove/open the other side
of this door. Is there a way to do this?

It looks kind of like this but one side doesn't open nor does it have
hinges.

Any help appreciated!

For what its worth the fixed door is holding the hinges for the left side
opening door. It is not a true fau french door setup -
