How to stream object loader? Custom Places in the map?

Hello everyone, I have already searched in several places already I researched here in the forum, there is this mod favela it contains textures and the .xml file would like to know how to install it, I need the object-loader to stream the mod? Another thing, there are channels on youtube where the creator has a workshop and custom seats on the fivem, would you like to know how this is possible? Via mapmaker? Or are they created in the map editor and streamed by object loader? In object loader when i put /start object-loader i received the access denied message.

help me to install this mod > http://www.gtainside.com/en/gta5/maps/106707-favela-grande-sao-paulo/download/1
