when clients send an email, it's added as a comment in a JSM issue (work item).
since it's coming from an external source, the text "ATTENTION: Ce courriel provient d’une adresse externe. / This message originated outside Company Name." is added to the comment.
I have the following rule, which removes that text from the comment: 
however, this leaves some empty space at the top of the comment: 
How could i remove this empty space?
I have tried adding another THEN action with currentComment.body.trim() but it didn't work. it added the text that had already been removed by the previous action and didn't remove any empty space. i assume that currentComment hasn't been updated with the changes from my first action, how do i get access to the latest edited comment?
any help is appreciated and thankyou in advance!
