Dynamic lightning - Torches in room that can only be seen when inside the room?

Hey there! I'm looking for a way to create a room with lit torches inside. I have dynamic lightning but I can't find a way for it to be a closed un-entered room with lit torches that the players can't see until they enter said room. The closest i've managed is to have the torches on the GM layer and manually switch them to token layer when they enter but this takes too much time and I'm busy with descriptions and player questions so I usually forget about manual torches. is there a way to make it automatic so when a token is dragged inside a room they can see the torches light but not before they enter said room? Many thanks to anyone taking time to read and answer!

Test out Line of Sight option.

Thanks for the quick answer...then I believe I'm missing on how to do torches because right now I have to make torches controllable by all players so they can see the light it emits...so they can see them across the whole dungeon...am I doing something wrong when creating torches?

A little bit. If you look just above the line of sight section, you will see the adding light section. Basically make the torch emit light and check mark it "all players see light" then go to the player's tokens and check mark the "has sight" option. ( Dynamic Lighting Example page shows you more info) to let them see the torch's light.
