Clear message

Hello, Guys! How are you?   I’m working on an APP that uses MQTT connector, and I want to clear my messages. Do I need to use some Nanoflow to do that?  *** Limpar = Clear   I tried to put the clear button inside of “Chat, From database”, but the button sets for all the messages that I recive.   Best regards, Augusto Santana
