function Get-DbaDbObjectTrigger {
    <#
    .SYNOPSIS
        Get all existing triggers on object level (table or view) on one or more SQL instances.
 
    .DESCRIPTION
        Get all existing triggers on object level (table or view) on one or more SQL instances.
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances.
 
    .PARAMETER SqlCredential
        SqlLogin to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
 
        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
 
        For MFA support, please use Connect-DbaInstance..
 
    .PARAMETER Database
        The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.
 
    .PARAMETER ExcludeDatabase
        The database(s) to exclude - this list is auto-populated from the server
 
    .PARAMETER Type
        Allows specify the object type associated with the trigger. Available options All, Table and View. By default is All.
 
    .PARAMETER InputObject
        Allow pipedline input from Get-DbaDbTable and/or Get-DbaDbView
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/ca
