Flow - Custom Connector - Api permission to Project Online (pwa)

[KrzysiekOle]

Hi

I'm trying create Custom connector and get data from my pwa. I know that I can do it with prepared connectors, but I want to prepare my own package.
Actions like: _api/web/lists is ok

but _api/ProjectData/Projects doesn't work = (403) GeneralSecurityAccessDenied.

Which Api permission I need to add to my Api registrations on Azure ?

When I use Actions -> Send an HTTP request to SharePoint, everything is ok

Best Regards

It seems that the credentials you provided are not acceptable.

Yes I know. As you can see I'm testing this on my tenant to whom I have full access. When I use "Send to HTTP request to SP" - everything is fine with simple Rest, I have access. But when I use Custom Connector - I use OAuth 2.0 and Azure Active Directory  credentials - My question is which Api permissions do I need to add ? (I repeat - in Custom Connector a simple rest such as _api/web/lists, {ProjectName}/_api/web/lists/getByTitle('{ListName}')/Items work well
