Would like to be able to access the custom extensionattribute properties from Flow. At the moment, the Office365 connector does not show any of the custom properties, and I have not found an easy way to do it. We at our business use one of the custom properties to store information that I need to get to from an approval Flow I am writing, and the Flow is based on that custom property to determine the level the approval needs to go up to, based on this property.
