Automate Microsoft Bookingwithme using Graph API

Question

Hi,

I need to automatically email my client requests for meeting appointments depending on my Outlook calendar availability from my custom CRM. I'm aware it's possible with Graph Event API, but for this, I need to build a custom interface form for the client so instead can I integrate with Microsoft's Bookingwithme service? Configuring the Bookingwithme page should be automated as well. or any other solution for the above criteria?
