For the short experience I've got with sentinel this should work. So I"m happy to merge as is 🥳

Thanks very much @simonasr

Thanks @damacus for a such fast response :)
When the new release could be expected?

I forgot to put a tag on it, so it wont get released 🤦🏼

I'll need to do a small update to release this by itself! Leave that with me 👍🏼
