MagnaBoard, assembly instructions

[Nissen11]

Hello!
I am going to install approximately 120 m2 of MagnaBoard (it supposedly comes from gröningboard - https://groningboard.com/produkt/magnaboard/?variant=10).
Unfortunately, I can't find any installation instructions, especially on how to design the joints. With or without air, do you use filler or how do you do it?
Does anyone know where to find installation instructions? Or know how to do it right? No guesses, please.
Thanks for the help
Nisse

Since the board is "897x2500x12 mm MagnaBoard straight edge," there will be a 3mm gap between each board joint for movement allowance.

Found one from 2017 but don't know if it's the one you're looking for or if it's applicable.

Ok, thanks for the reply. And then you apply putty? Just regular putty or is there a special compound for MagnaBoard?

Found one from 2017 but I don't know if it's the one you're looking for or if it's still valid.
