.net - Restore-PowerAppEnvironment cmdlet 引发错误“无法识别为 cmdlet 的名称”

Question

因此，我一直没有成功尝试使用 Microsoft.PowerApps.Administration.PowerShell 为 Dynamics 365 实例还原 PowerApp 环境。根据MS docs 的命令 语法和示例的示例

表明您需要先创建一个 pscustomobject，然后运行该 cmdlet。尝试创建 pscustomobject 时，Powershell 抛出此错误

备份cmdlet似乎可以工作，但是在还原时我遇到了各种问题。另外，只是尝试创建 RestorePointDateTime 会引发
