Azure bicep get application id of service principal-CodePudding

Bicep can be used to create a role assignment as follows:

resource RoleAssignment 'Microsoft.Authorization/roleAssignments@2020-10-01-preview' = {
  name: guid(managementGroup().id, RoleDefinitionId, principalId)
  properties: {
    roleDefinitionId: roleDefinition.id
    principalId: principalId
    principalType: principalType
  }
}

Where the principal type is 'ServicePrincipal', it seems the application id from the Enterprise Application page of the Azure portal is required:

Does anyone know how to acquire this programatically? If it's not possible using bicep then perhaps PowerShell?

To get the Application ID of service principal via PowerShell, you can make use of below command:

(Get-AzADServicePrincipal -DisplayName AppName).AppId

I tried to reproduce the same in my environment and got below results:

I have one service principal named ClientApp and got the Application ID of it successfully as below:
