The intended workflow with ADE is more that you run your editor/IDE and other tools inside of the ADE container, so you don't have to work with remote hosts and such. Typically, you would create a custom volume containing the tool, which ADE then allows you to load together with the base image. See the documentation which describes this process for the Atom editor:
https://ade-cli.readthedocs.io/en/lat...
The full setup for that can also be found in the following Git repository:
https://gitlab.com/ApexAI/ade-atom
And there is one for VSCode as well:

To use CLion like that you will have to create a similar setup yourself, I'm not aware of one already existing.
