Activating cell after button click (remove focus from the button)

Question

I have a sheet with one button (a shape) which is associated with an Apps Script function.

When I click the button it inserts a row and activates a cell in that row.

Then if I try typing, nothing happens. I manually need to click on the new cell to be able to enter new text...

How can I change the code to be able to immediately start typing just after the click of the button (without additional click on the cell)?

function above_same_level() {
  var ws = SpreadsheetApp.getActive();
  var row = ws.getActiveRange().getRow();
  ws.insertRowsBefore(row, 1);
  ws.getRange('A' + row).activate();
};

A workaround is pressing Esc right after the mouse click on the button.

It's slightly more comfortable than using mouse, but it's still an intermediate step.
