I am trying to add custom buttons to the Asset Toolbar in 6.3 to trigger Delete and Publish workflows specific to our content administrators. I have been able to successfully create the button to trigger the specified workflow as desired, but I can't get the button to show when overlaying /libs/dam/gui/coral/components/admin/contentrenderer/base/base.jsp to apps.
I have already overlaid other customizations for showing custom meta fields on the card, list and column views under /apps/dam/gui/coral/components/admin/contentrenderer/ successfully, but the base overlay isn't working. I have tested the functionality that I'm trying to add by modifying the libs base.jsp file, so I know that what I am adding and where I'm adding it should cause my custom button to appear, but for some reason it's not working when the file is overlaid.
No errors are being generated by this overlay.
Does anyone know of a specific problem with this overlay or a way that I can overcome this issue in order to add my custom buttons to the toolbar for Assets?
