I need to capture the hide/show event when I show or hide a column through the collumnpickerbutton.
Likewise, I need to capture the expand and collapse event of a column.

How could I do this?

You could listen to column store update event:

taskBoard.columns.on('update', ()=> {console.log('updated')} )
