Voice & Visuals Test links not giving me display

I have a skill fully functional and during the testing in VF prototype tool, ADC, and my Echo Show.

For some reason when I use the Voice & Visuals link for another tab, I receive a grey magnifying glass. I want to integrate this testing on my website but it must work first.

Can someone point me in the right direction?

FYI: I’ve also never seen my visual blocks (card or display) work via the VF prototype testing tool

I would also like to know if it is possible to see Cards on prototypes. Is it?
