Download commits, commiter data from GitHub to PowerBI

Good day,

Technical:

My team and myself are pushing our .pbip files to company GitHub, each saved in its own folder.

Scope:

I want to create a table, which then will be replicated for each report so user can see a changelog. 

The changelog should show: commit message | commiter ID | commit date | report name.

Current solution:

I was able to achieve all of it with below code:

Auth: Basic

let
    Owner = "git-owner",
    Repo = "git-repo",
    Branch = "pbi-reports",
    
    BaseUrl = "https://github.contosco.com/api/v3/repos/" & Owner & "/" & Repo & "/commits",
    
    Source = Json.Document(Web.Contents(BaseUrl, [Query = [sha = Branch, per_page = "100"]])),
    ToTable = Table.FromRecords(Source),
    
    AddFilesList = Table.AddColumn(ToTable, "Files", each 
        let
            CommitUrl = "https://github.contosco.com/api/v3/repos/" & Owner & "/" & Repo & "/commits/" & [sha],
            CommitDetails = Json.Document(Web.Contents(CommitUrl)),
            Files = CommitDetails[files]
        in
            Files
    )

Locally, everything is working perfectly.

Issue:

When I upload it to powerbi.com, I receive below error message during refresh:

Data source error{"error":{"code":"DMTS_OAuthFailedToGetResourceIdError","pbi.error":{"code":"DMTS_OAuthFailedToGetResourceIdError","details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"Failed to get OAuth resource, please make sure the OAuth is supported"}}],"exceptionCulprit":1}}}

So I have tried to pass PAT within the M code e.g,:

Source = Json.Document(Web.Contents(BaseUrl,
        [
            Query = [sha = Branch, per_page = "100"],
            Headers = [Authorization="Bearer PAT_TOKEN_IS_HERE"]
        ]))

But this failed as well.

Question:
Is there a solution to download all of the data I need without modifying the gateway or putting company data at risk?

I don't remember now what I did but I also received error about dynamic data sources - which was a new error, some progress, but I was not able to resolve it either.

Edit:

I also tried to use beta GitHub connector (PowerBI > Get Data) but I was not able to login since it was asking for credentials and combination of email/login and PAT (instead of password) did not work.
