@iko1 thanks for the contribution!

It looks fine and should be good to merge once we get the ongoing integration test issue sorted out.

It the future, check the issue to see if someone is already assigned. In this case someone else had asked to work on it and I assigned them.

Done, Thanks for the review.
Understood on the assignment, next time I’ll pick up a more complex issue and make sure it’s unassigned.
