Saving my Dorico iPad file to icloud

I’m reasonably certain that I’m missing something. But I’ve yet been able to find a way to save my work in Dorico for iPad to the icloud. Could someone enlighten me. I’m feeling quite old and stupid at this point.
Thanks in advance for your kind advice.

I don’t use the iPad version, but there are many threads here on file locations. Perhaps a search of the forum would help you?
