CAD Assistant- Custom Texture Adding Method

Hello Sir's,
Hope you are in great spirits!

I am actually trying to add my custom textures to the panels of my buggy, which is in obj format converted through Solidworks Visualize. But due to some constraints I am unable to detect the steps to follow for adding my custom textures to my model, I am using CAD Assistant . It could be really helpful if you could specify the method of adding textures to my model in CAD Assistant in detail, cause I am a newbie and am currently trying to get through various software's for my project for quite a while now. Respected Sir, I would be eagerly waiting for your reply and thanking you for helping me in advance!
