How to properly play shooting animation and aim offset?

Hello guys,

I would like to ask for some help.
I have to problems with animations, shooting especially.
I am using ALS V4, and I combined it with Weapon Component, the weapons are working correctly, but the animations are not.
I would like to play this shooting animation when I shoot with a rifle: Fire Rifle Ironsights 2020 11 28 15 29 58 - YouTube
But when I try to play the animation montage it won’t be played correctly.

The arms twitch a little but that’s all.
The other problem as you can see in the second video is that the weapon doesn’t look at the middle of the screen, where the projectile lands.

Can anyone help me in these problems?
Thank you for reading and thanks in advance.

can i see your fire weapon code

Here it is:

The animation is played for example at the end of the SINGLE SHOT MODE section
