Approval request displays account name not display name of the user / group

[ManfredWisniewski]

When a user requests an approval the request states which user or group will recieve the request. "Kann genehmigt werden durch"

In my Nextcloud the User accounts are managed via authentic and for security reasons the accounts are hashed (i.e. 7449d0b4210b296c471471855b...) but the display names shows the correct name of the user or group.

Almost all outputs in Nextcloud use the display name and not the account name, it would be nice if Approval could do this as well.
