Leave approval: send confirmation emails to requester and additional users

Leave approval: send confirmation emails to requester and additional users

Hello,
I use the approval feature of Zoho People > Leaves and I need to recreate the following behaviour.

Let's say I have this case:
1) Employee A is the one who's requesting the leave
2) Employee B and C are the approvers
3) Employee D and E is another employeed which needs to be alerted when leaves are approved

So I need the following:
1) When A requests a leave, an email is sent to the approvers (B and C)
2) When the leave is approved, the confirmation e-mail is sent to A, D, E and to the team email of A

So I was thinking about doing the following:



But for some reason I can't save the record and the reply-to field gets highlighted in red:



Is there a reason for this? How could I solve?

Thank you
