Knitting the second half of the Baktus

Problem description: I downloaded the "Good Vibrations" knitting pattern and have knitted the shawl as a Baktus halfway through. I urgently need help with the knitting chart labeled “Decreases.” Would anyone be kind enough to draw out the decreases for me in the repeat? I’m at my wits’ end because I’ve tried figuring out the decreases countless times but can’t seem to figure it out. If there are any costs involved, I’ll cover them.
I would really, really appreciate any help.

Hello Dinkel,
welcome to our forum. 
Have you already contacted the seller of the pattern? You can use this link or the contact details in the pattern. That should be the best solution. 
I wish you lots of success. 

Sorry to butt in, but didn’t eliZZZa pass away in 2021?
(At least that’s true for the eliZZZa who ran the YouTube channel of the same name. But maybe there’s another eliZZZa active here?)

Since I don’t have the pattern, I can’t help. But maybe there are other users who can explain the decreases.

The eliZZZa shop has been taken over.
I’ve written to the current shop provider and asked them to follow along and respond here in this thread.
