Equip the gun you want to attach attachment -> open up inventory, click the icon of the attachment -> it is attached! (icon name will update in a second to reflect the weapon it's attached to. Example: "Muzzlebrake" -> "Muzzlebrake [fa_m92fs]").

console keeps popping up Cannot find attachment manager, creating one... what should i do

Do you mean it appears once per round?

It means the mod is running on a map that has no preceding attachment manager, which is responsible for managing attachment entities, so it's creating a new one, as opposed to map that specifically spawns an attachment manager preemptively. It's meant for mapper to be aware.

TLDR: That's expected, you don't need to worry about it.

What command do I need to enter to activate it? When I look at the inventory, nothing comes up.

You need to own a gun and an attachment first to have them show up in inventory. Then do the thing described in the first reply above.

What is the inventory gun attachment button?

Click on the attachment icon the same way you do when you select a weapon in inventory.
