WebGL error message in an iframe

Hello @jorgearq @wojtek , im new to Shapespark .
I have imported a 3D Scene into an iframe as i saw on some previous asked questions here.
Now when i got the (view-switch) code from Shapespark API’s , it appears very good with the design i gave to it but it doesent function for example when i press (floor plan view).
And is showing me the WebGL error , i have made those steps with flags as @jorgearq showed here. Also my browser and graphics supports it .

Can anyone help !
