Replace torn GE freezer gasket

I need to replace a torn freezer gasket on the freezer of my GE Refrigerator. The model no. is TBX18LASERWH. I can’t see how it is currently connected (screws, tape, groove)? Please give me step by step instructions in how to do it. Your troubleshooting section had no entries.

You need to pull back on the gasket from the inside and you will see all the screws and the brackets that hold it on.
