Looking for guide for replacing touchscreen on Surface Laptop 4

Hi,

A few months ago I found a guide on iFixit to replace the touchscreen on my Laptop 4: just the screen itself, not the whole of the lid. It included, for example, guidance on where to place hot pads to soften the glue which holds the touchscreen in place in the lid of the laptop. So I bought a replacement touchscreen. Now I can't find the touchscreen guide on iFixit, but only a guide to replacing the whole of the lid. Can someone point me towards the guide I found before? Thanks.
