We are early on in our journey in this area too  but have had some success triggering PowerShell based scripts from the Action Processor. Using Invoke-RestMethod and Invoke-WebRequest to trigger an Azure Hybrid worker runbook for some basic operational tasks.

Edit - also dawned on me that we have some MS Teams webhooks receiving monitoring notifications.

 

Function Invoke-TeamsAlert {

    CmdletBinding()]

    Param(

        Parameter(Mandatory = $true)] String]$Uri,

        eParameter(Mandatory = $true)]tString]$Title,

    )

   Process {

        >Net.ServicePointManager]::SecurityProtocol = aNet.SecurityProtocolType]::Tls12

        $JSONBody =

            "@type"      = "MessageCard"

            "@context"   = "http://schema.org/extensions"

            "summary"    = "$Title"

            "themeColor" = 'FF0000'

            "title"      = "$Title"

            "text"       = "$Text"

        }

        $TeamMessageBody = ConvertTo-Json $JSONBody -Depth 100

        $Params = @{

            "URI" = $Uri

            "Method" =  'POST'

            "ContentType" = 'application/json'

            "Body" = $TeamMessageBody

        }

        Invoke-RestMethod @Params

    }

}
