a. please stick to English
b. Where is the problem? I see no question in your post.
I assume you know the restrictions that need to be met for video compatible to 4k UHD Blu-rays.
Personally I can't say much about it since I never used Scenarist UHD or ever had to author a UHD Blu-ray for that matter.
(don't even have a hdr capable display)
With a bit of luck some other folks here, who might have used Scenarist can help you in more details.
Since this section of the board is specifically not about Hybrid and as far as I know Scenarist UHD comes with (quite good) technical support which is included in the monthly/anual fees one pays for it your best bet might be simply using the support you paid for.
in general:
Assuming you want to create content that you only author (and not reencode) you would probably have to create UHD Blu-ray compatible content.
For the encoding one could probably use x265 with it's
--uhd-bluray option and make sure one properly signals the hdr information.

Ps.: you might have a better chance to find some help over at
https://forum.doom9.org since there are definitly a few Scenarist users over there.
