XF 1.5 Disable "Media" icon in Editor tool


Am looking to disable the "media" icon in the editor.
Is there a setting that allows me to do or should I look for custom template modifications?
Hello Rafass,
Thanks for the response. This definitely helps.
But is there a permission setting where I could show the "media" icon only to certain usergroups like Moderators, Administrators

and not show for the Usergroup - "Registered Users".
I see "Allow embedded media" only under Signature Permissions which is not effecting the editor tool in a post reply or create thread
Am I missing something obvious?
