Problem is you don’t supply a simple link

I would assume for the non tech people you would supply a simple code where you only enter the link from Google sheets but no. What is this?
[auto-iframe link=xxx tag=xxx width=xxx height=xxx autosize=yes/no]

Says “link=xxx” but how do you insert the link above and where?
Makes this an uninstall and waste of time, give a working sample at least not something we need to figure out
