javascript to start presentation of an embedded prezi

[Andras Schaffer]

Hi there,

I am working on a educational website to host prezi (classic) presentations among other tools for pathology residents. The embedded prezi has an unappealing thumbnail which I intend to cover with an overlay image. I would like to start the presentation by clicking on the overlay image, which will simultaneously hide.

Could someone provide me with the appropriate javascript code for this? I am not a programmer but so far managed to make progress on webflow.

I would greatly appreciate any input!

Thank you, es koszonom,
