Trying to import hands and gun model into roblox from csgo, how would I do it

(It feels like this should be in another place. If this is the wrong place to post, move it to the correct place or tell me another place to post.)

Hello!

I would like to import CS:GO’s Glock 18 gun viewmodel and animations into my ROBLOX game because I was inspired by others importing animations from other games and I wanted to try it out with CS:GO. I already have the gun model and arms in Blender. Two questions:

A: How to position the arms to the gun viewmodel arm position

B: How to import to ROBLOX

Thank you.
