"Microsoft Graph is the gateway to data and intelligence in Microsoft 365. Microsoft Graph provides a unified programmability model that you can use to take advantage of the tremendous amount of data in Office 365, Enterprise Mobility + Security, and Windows 10.
You can use the Microsoft Graph API to build apps for organizations and consumers that interact with the data of millions of users. With Microsoft Graph, you can connect to a wealth of resources, relationships, and intelligence, all through a single endpoint: https://graph.microsoft.com."

It seems that just about every language except VBA can be used to run this. Access is a database app and it would be great to be able to use it to collect data to feed into, say, Office 365 groups, users and so on.

The current method to split to SharePoint List at a 365 account was a good start, but is cumbersome to set up & support. The set up of a 365 account and then learning SharePoint is a real barrier. Documentation/support for this arrangement is very scattered between Access, 365 and SharePoint.

An integrated design whereby the Access developer can split the db with an option to put it in the cloud where the cloud is perceived as nothing but a folder would dramatically increase popularity of the product.

Not needing a pre established 365 account (or OneDrive or DropBox), not needing to know/learn any SharePoint is key - and just be BE file in a folder automatically set in the cloud. The ability to use classic desktop Access with no geographic/LAN limitation is huge - but right now just too complicated.
