Issue with sharepoint data source credential

Hi everyone,

I am not able to update the data source credential for the sharepoint after publishing to PowerBI services. Hope it is required before configuring the refresh schedular as flashing an error as Invalid while selecting "Basic" type of Authentication

I also would like to share that, the above sharepoint data souce is from our Microsoft sharepoint organization cloud and, it is very much accessible with the same credential.

Does OAuth data source credential is required for this authenticaiton ?

Thanks and regards,

Sahu
