Set custom Url with a string for the video player system

I am using the new VRC unity video Player and there is a string section called Video URL where I can place a working youtube URL. How would I set this URL using an Udon graph script?
Within the graph, I found the VRCUrl Var and made it public but I want to convert a string into that using a keyboard system that outputs a string. How would I go about this?

i was wondering the same thing. this is missing from my world…
