I'm trying to hide(remove) interactive report 'Control Panel' captured below so that users can't change the report whatsoever.

I've found this thread here.

Remove interactive report 'Control Panel' script no longer working
Tried #1 and #2. Both doesn't work in APEX 5.
Per #3, I'm not sure I put the code in the right place. But I did like below and it doesn't work.
Can anyone help me to hide Control Panel as soon as page opens ?
1. In the page footer
<script type="text/javascript">
$x_Hide('apexir_CONTROL_PANEL');
</script>
2. (page inline css section)
table#apexir_CONTROL_PANEL {display:none;}
3.implement a dynamic action on the page to hide the control panel using: this.affectedElements.find( ".a-IRR-controlsContainer" ).hide(); on page load.
