Projecting Widget UI on a mesh (like a scroll or parchment)

Hello, can someone please guide me step by step on how I can get a widget UI menu to be properly projected onto a mesh like a parchment or scroll or paper so thats its actually part of the meshes material and looks like its actually written on to the paper mesh. Like how does this widget component and render target and all this stuff actually work with a mesh and how will it actually project and work with mouse clicks. Thank you!!!
