FiveM QBCore Script

i have QBCore script it’s already working good but i wanna add some features on it like add some buttons with js to make link with another scirpts like (Priority police Script + button to make player can write there the number of the cam to open cam of robbaries, add more scan of how much ppl in specific area using Polyzone – it’s using now getDistanceBetweenCoords – and it’s only show where’s the police in the map, i wanna make it it’s show how much police officers in the area + how much normal player in the area )
