Commandblock Output = False not working? [duplicate]

I have a command set as follows:

/tellraw @p ["",{"text":"[Level 10] Medium ","color":"green","bold":true,"clickEvent":{"action":"run_command","value":"/setblock 479.5 13 309.5 redstone_block 1"},"hoverEvent":{"action":"show_text","value":{"text":"","extra":[{"text":"Click to Play"}]}}},{"text":"[BOSS] ","color":"light_purple","bold":true}]

Which will show a clickable message in chat, which when clicked will place a block, however I do not want any output in chat. I have done:

/gamerule commandBlockOutput false

However after cliking the text, the following can be seen in chat:

Block Placed

Is there any way to prevent this from happening?

Is command block output false?

To get a repeating command block, players must use the /give command like so: /give @p minecraft:repeating_command_block <amount> . Players can also change a normal command block into a repeating command block by selecting the option in the command block GUI.

How do you activate a repeating command block?

The "commandblockoutput" gamerule, when set to false, will disable that chat output.

What does Gamerule Commandblockoutput false do?

Go into your world settings. Scroll down to the cheats section and you should see "Command Blocks enabled" or something like that. Flick that off and the command block should stop. If you don't want your chat to be spammed like that, type /gamerule commandblockoutput false .
