PBRS scheduled refresh from Sharepoint Online - issue with credentials

[Teemu]

Hi,

I am trying to setup scheduled refresh on PBRS but neither of Authentircation Types that are available at PBRS work with Sharepoint Online. This documentation says that PBRS does not support OAuth-based authentication for model refresh. 

So, am I encountering this problem because PBRS cannot connect to Sharepoint Online or could it be due to PBRS configuration or something else? 

My goal is to setup scheduled refresh from a shared location. I am trying to use Sharepoint online as were using Teams and our files will be stored there. If PBRS does not support scheduled refresh from Teams/Sharepoint Online, is there any workaround for this?
