Website -> Count Button Clicks and never reset

Holaaa

I wanted to create a simple website containing a button. If I press the button 5 times, it says 5. When I refresh the page, it should still say 5.
And when You load the page, it also says 5 and you can go on clicking.

I know how to build a counter for ONE session and one user, but I have nooo idea how to implement it to be stored “online”.
I am a beginner -> do you guys have any ideas on how to go on?
