Hi, how can I make a reflection to be applied to the glass material like this?
In practical make the glass reflect the surroundings without seeing inside 
You could always use a part with Plastic/Smooth Plastic as material and turn the Reflectance to 1.

in this way it reflects the skybox but not the environment around it such as the player character or objects.
Alright then, try setting the Material to Metal and see how that looks like. Turn up graphics.

Roblox currently doesn’t support proper reflections aside from interior cubemaps. A trick I use sometimes is using a part with a Glass material, making the transparency something like 50 and giving it an invisible Highlight. The distortion makes it look like there’s a reflection, but it can look odd a lot of the time.

You can actually script it, there is actually a free model that does that. Although keep in mind performance is costly!

Breaks the engine solution but create a Blender Mesh that has a lot of faces, each one will be each square of that reference image you gave.
Import it to Roblox give it a Highlight (it can be 0 on everything as long as it is active) and then using the console set up
game.workspace.part.reflectance = 0/0 (ending as NaN value)
make sure the material is glass and has some transparency.
Warning; This only works if your Studio Graphics levels are max (21), not sure if in Roblox it means maximum graphics.

you can try using SurfaceAppearance instance and experiment with MetalnessMap and RoughnessMap shadings, only if it’s a mesh
