1. Create a function that should fire upon an event being triggered. Example: ` function WelcomeUserToRoom { [PoshBot.BotCommand( Command = $false, TriggerType = 'event', MessageType = 'PinAdded' )] [cmdletbinding()] param( [parameter(ValueFromRemainingArguments)] $Dummy )

   Write-Output 'YO YO YO' } `
