Connecting to Team Site's on SharePoint to get data from data files shared on the team site is a frequently requested feature by the users. The O365 connector does that but in a very technical and is not simple, intuitive for use like select and load or drag and drop also, it has other issues like it requires access to all the data on the team site's (becomes a problem if there are team sites with sensitive PII/SPII data). It is also something not supported in the present web data connectors.
