Batch notifications with external access

Hello everyone,
I’m looking for some help setting up an external access link on batch notifications. We are running Jira Core Server and I believe the file we need to modify is IssueUpdateBatchers-header.vm
I would like to create a new line for cloud users that references “add comment” or “view issue” so they get taken directly to the resource with an external IP address.
Thank you in advance for any assistance!

#if ($header.issueUrl) $i18n.getText('issue.update.batch.mail.header.viewissue') #end   ·   #if ($header.addCommentUrl) $i18n.getText('issue.update.batch.mail.header.addcomment') #end
