Chromium is a special case, you'll have to force-enable accessibility to get the OSK to show up. See https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1697641/comments/7.
For other applications (including gedit and libreoffice), the OSK should show up if you enable the OSK in the accessibility settings.
