How to combine two specific scripts together?

[Mazi1981]

Hi guys. I´m new to this place and bad coder, so sorry to write here like a rookie.

I read many manuals how to combine two scripts together, but didn´t help me with my task. Because I´m coding analphabet. And yet, I need the coding.

This script bellow (highlightNotes) , works very nice alone. But I need to execute it everytime when I edit the Google Sheet. Probably merge it with function onEdit(e) ?

/**
Here is the script, that fills the background color, where Note is inserted.
*/

function highlightNotes() {

  const sheet = SpreadsheetApp.getActiveSheet();

  const range = sheet.getDataRange();

  const notes = range.getNotes();

  const orange = notes.map(row => row.map(note => note ? 'orange' : ''));

  range.setBackgrounds(orange);

}

That script executes only when I play it manually. I need to keep it active in background all the time.

I tried different combinations, how to merge onEdit and function highlightNotes(), but I´m really bad with codes.

Can someone write it completaly for me?

Example of my sheet is here https://docs.google.com/spreadsheets/d/1qG_P_EYnEw28pfIQew7ZbpmvgO6Ie5D0HpsezoCMNCg/edit?usp=sharing

Thank you guys, Martin.

Thank you Marc. OK. Will ask "There".

I thought (as a beginner in coding), that it could be a simple stitch of these to scripts together, with a little efford.

So it seems, is not.

Thank you, Martin.
