Right-clicking on a folder or file brings up the following, but your integration is not appearing as one of the integration options as designed.
Troubleshooting Steps
A few things can cause this:
1) At the user level, the integration has not been "added" via the app store.
For example, go to your All Files page and click on the circle in the top right-hand corner that contains your initials or photo. Choose Apps from the drop-down menu and search for Docusign. Once you click on the integration name you'll see an Add or Remove button.
The desired integration must be added in order for this to work as desired.

2) At the Enterprise level, the integration is not set to available in Individual Application Controls of the Admin Console.
You can check this by navigating to the admin console and clicking on the gear in the top right-hand corner for business/enterprise settings. Then, go to the Apps tab and search for the application. This is only applicable for published applications.
