General ticket chat has two entity types that a file can be related to:
GENERAL_TICKET_CHAT— file attached to the chat itself, without a message being generatedGENERAL_TICKET_CHAT_MESSAGE— file attached to a specific chat message
In general, a file is related to the message it is being sent with. When there is no message to be sent, the file can also be related to the chat itself.
