Adding a static mesh into animation editor?

Hi, I need to create a weapon grabbing animation, and without actually seeing the weapon in the animation editor I can’t create a precise animation. I need to go back to the level, play the game to see if it fits it, and I can’t even understand how much left/right/forward I need to modify the animation! Is there a way to add a static mesh into animation editor?
Yes, I create all my animations inside Unreal Engine. I don’t want to use anything else, it’s awful
