How to set a spot for a car to spawn on a map

Hi, I need help with setting a spot for a car to spawn in a circut de la sarthe map I imported from AC. I pretty much just need info on how to do this. I tried playing around with the json files but it didn't work. Tell me if I should put some screenshots of screen recording for more info.

 

nm I figured it out

 

actually I take that back. I think I'm trying to edit the right json, this is the folder path I'm in, lemans_test / main / missiongroup / playerdroppoints / items.level json. Here is a screenshot of it, please tell me how I can edit it to get the vehicle to spawn in the spot I want it to on the map.

Is the area circled in red the only thing I should edit or is there more?

 

In-game if you open the world editor, you can create/move the vehicle spawn sphere.

 

Ok thanks, I'll try that.
