How to adjust the position of the melee weapon?

I’m new to this, and wish to get some help from experts

Below screenshot show the poolcue weapon holding by character.

Would like to know which line in the meta.files should i edit to correct the location of the weapon, OR i should edit the location in zmodeler? I did edit the location in zmodeler and export it back, but when i launch the game, spawn the weapon, and fivem will crash.

Please help!

Thanks
