Hey thanks im glad you're enjoying it.
I didn't make a glass texture at all, it was done in engine in UE5 basically building a shader using the material properties in the engine. I dont remember how i built this one specifically, but there are loads of glass shader tutorials for UE5 and other engines.
Sadly that means there's no 1 texture i can give that'll work on all engines. If you're using godot for example or unity, my shader wouldnt work at all. You need to make it in your engine of choice
