Bill, what I would do is create a main Placeholder and add the Google Calendar code into its Body. I usually tweak W&H to 100% rather than pixels but in this case only do it for Width. You get the code from https://support.google.com/calendar/answer/41207?hl=en.
Set to Share with variants and in the Variant set the Placeholder to fit the Variant width.
Now Create Web Blocks for both.
You now have a Google Calendar Web Block.
If you skin a Calendy WB and replace its code with Google's you are still left with the Edit in a Browser link that goes to Calendy.
I have yet to find what Xara includes into the WB structure so it can be altered.
