Omnichannel - offline Mail not forwarded to Department Mail-Address

Description:

We have several departments in Omnichannel/Live Chat, with different mail addresses to which messages should be sent when Live Chat is offline. Unfortunately, this does not work. The emails all go to the mail address that is set in Settings > Omnichannel > Live Chat.
Unfortunately, the mail address set in Omnichannel > Departments > Edit > Mail address is not considered at all and no offline messages are sent there.

Steps to reproduce:

1. Omnichannel
2. Departements
3. Edit
4. Give Mail-Address
5. Try offline Live-Chat

Expected behavior:

The offline Message should be send to the Mail-Address which is set for the departement

Actual behavior:

It send the offline message to the mail-address, which is set under general settings for the omnichannel.

Additional context

Relevant logs:

Start by reproducing the offline Live Chat flow with a department mail address configured under Omnichannel > Departments, then trace how the destination address is selected. Done means an offline message for a department is delivered to that department's configured address rather than the general Omnichannel address.
