Pause Javascript when executing it in browser console

Question

I need to execute a Javascript in the console of Chrome with some delay. How can this be done?

The reason I need this is that as soon the focus changes from the webpage (or a certain element of the webpage) it is redrawn. Therefore I want to start the script I execute in the console with a few seconds delay so I can change the focus to the right element on the page I am working with.

function delay (ms){   return new Promise(resolve => setTimeout(resolve, s));  }
