Web data source credentials get cached, cannot be edited or cleared

[ToddChitt]

I'm trying to get data from Microsoft Graph API at this site: https://graph.microsoft.com/beta/users?$extract=manager using the WEB connector. 

I paste in the address in the URL box then click OK.

Next page wants my credentials, which for this case are (I think) Organizational. So I select the option and enter the username and password.

I get back an error message "Unable to connect" Details: Access to the resource is forbidden.

So I click EDIT with the expectation that I can EDIT those credentials. What I CAN edit ONLY is the URL. The credentials are cached somewhere.

I check Recent Data Sources in the hopes that I can clear them there, but nothing is listed. 

HOW DO I EDIT THE CREDENTIALS FOR THE WEB URL CONNECTOR.

I tried signing out, restarting the desktop. Nothing seems to work.

Please give me a way to EDIT the credentials.

Addendum:

Re-booting the machine had no affect.

Re-installing Power BI Desktop had no affect.

@ToddChitt ,

Click Edit Queries-> Data source settings and click "Clear permissions" as below:

I had to Clear ALL permissions because I couldn't find the entry in the list. And since the query never completed, it doesn't show up in the Current File list.

My oopinion is that the EDIT button (after the connectin fails) should allow you to do just that, actually EDIT the CREDENTIALS. If you mis-type a password, or want to try a different authentication method, it's a lot of click-smithing to get to something that should be accessible right there.

It's a global functionality thing. Other data sources behave in the same way.
