Do you have a basic understanding on how the shading tab works in blender?
Click the face in layout mode (or select the face material) and go to the shading tab (at the top somewhere) and see if there is an orange box that says 'image texture'. If not, make sure a little box labeled 'use nodes' is checked. If there are still not an orange box, go to add, > texture > image texture. Press open on the orange box (you can do this if you already have an orange box) and locate your texture that you downloaded. It should be with the model you have downloaded. If you need more guidance, feel free to message me on discord so I can share my screen. Discord: rypie109 (same pfp)
