Need help converting from Sibelius to MuseScore (sib => MusicXML)

Hi everyone!

I'll be conducting a cantata soon and two of the scores that I need are in the SIB format, I need to work on them in MuseScore. I don't use Sibelius, just Finale besides MuseScore, so I was wondering if anyone here with Sibelius could do me the favor of exporting them to MusicXML with the Dolet plugin? I'm not sure what version of Sibelius these were worked in, but they're supposedly from 2017. Please, if you can give a fellow musician a hand, reply to the thread and I'll get in touch; I (and the choir) would greatly appreciate it.

Best,
I. Josue Quintero A.
