RAK7431 Downlink FPort Definition

Hello, everyone!

We are testing out RAK7431 Remote functions for deployed RAK7431 nodes. Currently the AT Command Manual includes the following message fport list:

Regarding fPort 200~205, it seems that there are already commands (and formats) for remote restart and LoRa read/write config features and those commands can be sent through fport 130. Are these specific fPort (200~205) dedicated for non-transparent mode downlinks or alternatives for downlink messages for all mode? Or are these fPort served for other purposes?
