Minecraft command block timer?

I want a comandblock that triggers every 10 minutes (1.16.5) but with the scoreboard I can't do it because in every tutorial a test comandblock is used for the "Dummy" command but it says that there's no test command.

You could make a timer with funnels and items

Thank you that helped me a lot

I have another question, I need a 600 sec timer, but a funnel only has 5 slots

ot

Route the signal from the funnel to a second funnel timer
