Client id?

Im trying to use the Power BI module in PowerShell:

https://www.powershellgallery.com/packages/Microsoft.PowerBI.PowerShell/1.2/Content/Microsoft.PowerBI.PowerShell.psm1

But as far as i can understand, i need a onprem webap to register an app in azure and get a client ID? Im on a cloud only environment.

    //Client ID is used by the application to identify themselves to the users that they are requesting permissions from. 
    //You get the client id when you register your Azure app.
    {"client_id", Properties.Settings.Default.ClientID},

    //Resource uri to the Power BI resource to be authorized
    // https://analysis.windows.net/powerbi/api
    {"resource", Properties.Settings.Default.PowerBiAPI},

    //After user authenticates, Azure AD will redirect back to the web app
    {"redirect_uri", "http://localhost:13526/Redirect"}
