Hi Alex,
Greetings from Syncfusion support.
We would like to inform you that we have already considered
to provide support for SharePoint provider in the File Manager component.
Currently, we do not have an immediate plan for this feature. However, it will
be included in one of our upcoming releases. Generally, Syncfusion plans
features based on customer count, feature requests, and Wishlist plans.
You can track the feature status through the below feedback
link.
