PRE-BUILT connection for Microsoft Outlook, Calendar, Teams

Im building a CRM and I’d like to have Microsoft be a Pre-Built connection to have it integrate. Having issues wtih Client ID, Secret ID etc. Not working, going in circles. But, to be able to have where I can SIGN in to Microsoft simply to have it integrate would be great. I can do that with GoHighLevel now.

Also, either have the ability to create a “Calendly” like features into my CRM, or be able to integrate Calendly into Base44, whatever works.
