How to add Help in Webstorm

p5.js Beginners
1

Id like to autocomplete and reading help while coding of p5.js in Webstorm…
For example if i want write:

  // Draw the arc.
  arc(50, 50, 80, 80, startAngle, endAngle, PIE);

some kind of:
arc( and as a tooltip when mouse is over inform the parameters and its value, ex coorx of the circle, coordy of the circle, startangle and endangle )

So i dont need to go to the p5.js reference…

I prefer to use Webstorm…but VSCodium would be ok
Thanks
