If this is some sort of special repatriation flight (as it appears to be since it's for Europeans), you might need some link available through the consulate, either through a website or email. Have you tried contacting the local French embassy or consulate? They might know more than your own consulate (Finland?). In fact, have you registered with the relevant consult/embassy? [This might have resulted in having information about the flight sent directly to you.]
Look at the thread on repatriation flights in the newish FT COVID-19 forum for information on the various ways these are organized (including the ones operated by regular commercial carriers) and general procedures. IIRC there are links in the wiki for repatriation flights for Europeans stranded in various locations.
