This will get you started:

[API/dev resource] screenshot-basic - make screenshots of clients' games!

screenshot-basic is a basic resource for making screenshots of clients’ game render targets using functionality already existing in FiveM. See the repository README for more information. This is only API, no commands or interface get exposed to end users with only this resource.
