Oauth option missing when providing credentials for odata source on powerbi.com

[araneus]

I have an odata data source created using PowBI desktop with organizational acount authentication choosen. After publishing my dataset to PBI service I'd like to configure my data source for scheduled refresh but after publishing the source cannot be scheduled becuse credentials are not filled:

When trying to edit my credentials, OAuth option is no longer showing so my credentials cannot be entered:

Having the same problem.  Four years later.   There must be a solution.  

Where is OAuth in the connector settings in power bi service?  

I'm reading I need that to solve my problem which is:   Successfully connecting power bi desktop to an excel sheet on OneDrive/SharePoint but, after publishing to the service, the service generates errors when attempting to connect.    I'm using the same credentials on desktop (which works) and pbi service (which doesn't)

Anyone?
