Help please!!!

The Squarespace page in question:
https://www.prest.group/first-consultation

Here are the options from MS Bookings:
link: <a href='https://outlook.office365.com/owa/calendar/PrestGroupintrocalls@prest.group/bookings/'>Schedule online</a>
https://outlook.office365.com/owa/calendar/PrestGroupintrocalls@prest.group/bookings/

Embed/iFrame code:
<iframe src='https://outlook.office365.com/owa/calendar/PrestGroupintrocalls@prest.group/bookings/' width='100%' height='100%' scrolling='yes' style='border:0'></iframe>

Troubleshooting so far:

• Checked this forum and found one other thread related to this so I:
  • Added the CSS code around block height proffered in the only other example
  • Ensured my page was published publicly from MS by using an incognito page in Edge, Chrome and Opera
• Manually dragged the embed size to full width and a ridiculous height to avoid that being a display issue
• Attempted both the link with and without the href tagging
  • It says it's found when in the code box, but the page displays "Enter a valid embed URL or code"
• Tried the iframe embedding
  • That shows nothing at all after pasting the code?

I'm so open to suggestions right now!
