At the point in the NDR clip where they explain skydivers jump out of the plane according to plan (...) the underside of the empannage is visible. Based on that, I would say it's D-FLEC of Skydive Binz: the word 'BINZ' is visible and the colours match FLEC. Their other two Ce208s have a slightly different scheme, if the photos I found match the current situation. See

this photo.
RIP the 65-year old pilot...
Edit: confirmation or so it seems, by
ADSB Exchange.
Additionally, FR24 puts FLIC in Chrcynno (Poland) for the weekend and FLOC at home in Dahlemer Binz last Friday.
