How to add a climbable ladder in fivem with codewalker

How can i add a ladder in codewalker that is shown in fivem. I tried all the props with ladders in codewalker they appear but in fivem the ladder is invisible and i need a ladder to climb on something. I m new to mapping and mlo things

not all ladders work and have collisions

Go to this site and search, mouse over the highlighted circle (+26) to see if they have embedded collisions.

Unless you can edit them in Blender, you will have to search and test
