Adding a new font type to Storyline 360

I have been working in Rise 360 until now, where I have uploaded our approved brand font - Josefin Sans. I am now upskilling and working in Storyline as well, looking to embed a range of Storyline slides and interactions into my Rise 360 training program. I hope I'm missing something, but it seems there is no way to use the same font in Storyline?

Please advise. It is most disappointing to get this far into our development and find we can't use the same font across the different apps for seamless presentation. Hoping for an easy fix to this issue. Thanks!
