我已经下载了这个powershell脚本，它将Power BI报告内容复制到一个新文件中，但是我不知道应该在哪里输入SourceReportId、SourceWorkspaceId、TargetReportId、TargetWorkspaceId等参数值。
脚本也可在此处获得：https://github.com/JamesDBartlett3/PowerBits/blob/main/PowerShell/Copy-PowerBIReportContentToBlankPBIXFile.ps1

  .SYNOPSIS
    Function: Copy-PowerBIReportContentToBlankPBIXFile
    Author: @JamesDBartlett3 (James D. Bartlett III)

  .DESCRIPTION
    - This script will copy the contents of a published Power BI 
      report into a new report published from a blank PBIX 
    - This solves the problem where a Power BI report originally 
      created in the web browser cannot be downloaded from the 
      Power BI service as a PBIX file.

  .PARAMETER SourceReportId 
    The ID of the report to copy from

  .PARAMETER SourceWorkspaceId
    The ID of the workspace to copy from

  .PARAMETER TargetReportId
    The ID of the report to copy to

  .PARAMETER TargetWorkspaceId
    The ID of the workspace to copy to

  .PARAMETER BlankPbix 
    Local path (or URL) to a blank PBIX file to upload and copy the source report's contents into

  .PARAMETER OutFile 
    Local path to save the new PBIX file to

  .EXAMPLE
    Copy-PowerBIReportContentToBlankPBIXFile -SourceReportId "12345678-1234-1234-1234-123456789012" -SourceWorkspaceId "12345678-1234-1234-1234-123456789012" -TargetReportId "12345678-1234-1234-1234-123456789012" -TargetWorkspaceId "12345678-1234-1234-1234-123456789012"

  .NOTES
    This function does NOT require Azure AD app registration, 
    service principal creation, or any other special setup.
    The only requirements are:
      - The user must be able to run PowerShell (and install the
        MicrosoftPowerBIMgmt module, if it's not already installed).
      - The user must be allowed to download report PBIX files
        (see: "Download reports" setting in the Power BI Admin Portal).
      - The user must have "Contributor" or higher permissions 
        on the source and target workspace(s).
    
    TODO
      - Testing
      - Add usage, help, and examples.
      - Rename the function to something more accurate to its current capabilities.
  
    ACKNOWLEDGEMENTS
      This PS function was inspired by a blog article written by 
      one of the top minds in the Power BI space, Mathias Thierbach.
      And if you're not already using his pbi-tools for Power BI
      version control, you should check it out: https://pbi.tools
