function Enable-DbaReplPublishing {
    <#
    .SYNOPSIS
        Enables replication publishing for the target SQL instances.

    .DESCRIPTION
        Enables replication publishing for the target SQL instances.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER SqlCredential
        Login 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 SnapshotShare
        The share used to access snapshot files.

        The default is the ReplData folder within the InstallDataDirectory for the instance.

    .PARAMETER PublisherSqlLogin
        If this is used the PublisherSecurity will be set to use this.
        If not specified WindowsAuthentication will be used - this is the default, and recommended method.

    .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/catch.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
