AR Lens for furniture that change materials on click

[tight osprey]

I am trying to create one AR lens with one chair, which have one base color and there are 2 more AR color buttons, or you can say 3d objects. So now if I click on one of the buttons, Chair color need to change.

You can achieve this with UI buttons and behavior script. For behavior script use Set Material Parameter response

Thank you for the reply, I don't wanna use UI buttons, I am using 3D Objects as a button.
