Dragino LHT65 V3 -> Cayenne


I have two Dragino LHT65 sensors, which I have used in recent years on the V2. One of the two sensors is still connected to the V2 and I am using Cayenne to visualize the data (graphics). I got my other sensor and bought a TTIG gateway, everything works fine on the V3 but when I want to put this sensor on Cayenne, the data is not viewable (I only have the “location”, no temperature widget ). I’m sorry if the answer to my question has already been posted, but how do you relate the TTN V3 to Cayenne? (I created a webhook in “integration” but I don’t know what else to do).
Thank you !
