How to add Security groups to Sharepoint groups?

Question

Hello,

I'm creating a Microsoft Team programmatically, via Graph Calls. After creating a Team, a sharepoint is automatically created and I'm creating a folder structure in the Sharepoint.

I want to add security groups to the sharepoint groups

In the screenshot below you see the Sharepoint Groups

Here you can see I can add a security group to the Sharepoint group by useing the user interface.

This all works, but I want to do it programmatically. Are there Graph calls I can use? Or do I need to use Powershell or C#?

Thanks for reading and I hope someone can help.

Hi @Romian Tairovski ,
I will recommend you to use PowerShell, in which case your best bet is the Add-SPOUser cmdlet, which "Adds an existing Office 365 user or an Office 365 security group to a SharePoint group."
Here is the example

$SecGroupName = "TestSecurityGroup"        # The security group DisplayName  
$SPOGroupName = "TestSharePointGroup"      # The SharePoint Online group  
  
# Get the SharePoint site  
$SPOSite = Get-SPOSite "https://contoso.sharepoint.com"  
  
# Add the security group as a member of the SharePoint Online group  
Add-SPOUser -Site $SPOSite -LoginName $SecGroupName -Group $SPOGroupName
