Formatting Reaction Send to Chat super secret roll message

Can a super secret roll message be formatted to have extra lines? I'd like for my output to look like below, with each on a new line. I've tried %NEWLINE%, commas, </br>, braces, but what I've tried didn't work. It would say "There was an error with your formula. Please try again." or some of the text would be displayed to PC (giving away that a roll was made).

Hi Jason, You can now use roll templates and inline rolls with /s and /ss.  You could do something like; /ss &{template:default} {{name=test}} {{roll1=[[1d6]]}} {{roll2=[[1d6]]}} or /ss &{template:default} {{name=test}} {{=roll1=[[1d6]]%NEWLINE%roll2=[[1d6]]}}

Thanks for the help. I was able to paste the second one in, then modify it with some experimentation. Do you know what the code is based on? javascript or something else? /ss &{template:default} {{name=Passive Perception check}} {{=@{instigator_name}: @{selected|passive_wisdom} %NEWLINE%roll= 1d20 }}

It's just roll20's proprietary roll template and macro rules. There's  more info on the wiki. My example is using roll20's default roll template, but you could also use the roll template for your character sheet.
