Add filter to modify email messages from email-template

[rtBot]

Migration Note: This issue was originally created by @pranali333

There is not any hook available which can allow modifying any message from email template. We only have all individual hooks to change any specific message.

Solution :

Add below line,

$redux = apply_filters( 'rthd_email_template', $redux );

to rtbiz-helpdesk/admin/helper/rthd-functions.php line number 1691 before below code snippet:

if ( ! empty( $key ) && isset( $redux[ $key ] ) ) {
        return $redux[ $key ];
    }
    if ( $all ) {
        return $redux;
    }
