We have turned off the ability for staff to create their own LTI integrations via External Tool but still would like to have the capability for staff to add preconfigured tools to their courses pages.
Does anyone have any experience of this? Or know if it is possible?
We have tested various ways, but seem unable to have the set up we require.
When we disallow allow course specific permissions then users are met with this error message:
When we allow it then users still seem to have the ability to create external tool. They can create an instance okay, 
however when they save and edit it again then there is plus sign option and users can then add an external tool from here.
These are the configs we have currently set up:
There seems to be a varied ability depending on which LTI we try and set up. Some work as expected (i.e staff can set them up on their courses) given the configs, but some do not.
We ideally would like staff to be able to add a course instance themselves from a preconfigured tool, with the ability to add custom parameters or use the Select Content option
Any advice appreciated.
