Update Datasource Credential Using Only Powershell and RSA-OAEP Authentication

I am trying to figure out how we can update credentials for a power bi datasource in our gateway via the API only using powershell, we want to be able to automatically rotate credentials just running...

This is how we eventually got it working in just powershell, if anyone is interested:

I am trying to implement this with OAUTH2. Is the flow for OAUTH2 similar to Basic Auth? Can you provide some pointers for OAUTH2 implementation?

  I haven't tried it using OAUTH2, and we actually ended up switching over to doing it in python. But from some inital searching I imagine you could change the body to be like this:
  
  $body = @{ "type" = "OAuth2", "typeProperties" = @{ "clientId" = "<client-id>", "clientSecret" = "<client-secret>", "tokenUrl" = "<token-url>", "resource" = "<resource>" } }
  
  But I can't say for sure, sorry.

    We're dealing with this encryption so that we can create a data source via API's I haven't had much luck with the API call. Were there any updates/improvements to this PowerShell Script? Please share any thoughts as we're trying to automate some of this process to extract password from our internal vault and call "Create datasource" API but it doesn't seem like its a simple call.
