I want to display the text in two rows.
<br> does not work

It looks like the indicator ignores all line breaks. I tested it with \n, <br>, and textformatting.newline, and none of them do anything, even when you use Advanced Formatting with Arcade. You may be out of luck, unfortunately.
As a workaround, you could mention the text under General Options > Title.
