Using weapons from ArmA / DLCs within SOG - how to access BIS_fnc_arsenal ?

Hi,

I am trying to open the general BIS_fnc_arsenal within a VN mission, e.g. the first mission of the campaign/coop.

Here is what I do:

#1 Start Server (local or dedicated)
#2 Launch coop mission
#3 execute "call BIS_fnc_arsenal" to see the arsenal and to test weapons/stuff

Only sometimes I see the full arma arsenal with all stuff from different DLCs/mods, but most times I can only choose from SOG arsenal items.

How can I get access to the full arsenal within a coop mission?

Here is what it looks like:
