To install the Microsoft.Graph.Applications module in an Azure Function, you can use the Install-Module cmdlet from the PowerShell command line, as you tried. However, it looks like you encountered an error when trying to do this.
There are a few things you can try to resolve this issue:
Make sure you have the required permissions to install modules in your Azure Function. If you are not the owner of the Azure Function or do not have the necessary permissions, you will not be able to install modules.
Make sure that you are using the correct syntax for the Install-Module cmdlet. The correct syntax is Install-Module -Name <module name>.
Make sure that you are running the Install-Module cmdlet in an elevated PowerShell window. This may be required if you do not have the necessary permissions to install modules.
If you are still encountering issues after trying the above steps, you can try manually installing the module by downloading it from the PowerShell Gallery and placing it in the correct location in your Azure Function. To do this, you can follow these steps:
Download the Microsoft.Graph.Applications module from the PowerShell Gallery (https://www.powershellgallery.com/packages/Microsoft.Graph.Applications/).
Extract the downloaded module to a folder on your local machine.
In the Kudu console for your Azure Function, navigate to the D:\home\site\wwwroot\Modules directory.
Upload the extracted module folder to the Modules directory.
After uploading the module, you should be able to use the Import-Module cmdlet to import it into your Azure Function.
