How to show subtitles in D5 for IPad

I try to show a subtitle in a score using the IPad version and I can’t figure it out , how to do it. It should be possible in the Engrave mode, but how ? If I try to write anything in the green fields , a big popup window pops up for the formatting and hides the field, in which I should write the token . So, how does it work?

Dorico for iPad doesn’t have the same frame editing capabilities as Dorico Pro on the desktop, I’m afraid.

You could potentially override the flow heading automatically shown above the first flow? Or copy in a multi-line bit of text to the title field, although you can’t resize the title text frame on the iPad.
