I'm currently building a CMS using Drupal 8 hosted in Acquia Cloud. At this time of the process, the goal was to do the setup of URL Patterns.
After some going around, found out the installation of modules isn't actually as straightforward as clicking a button, inferred from seeing the following screen (doesn't appear that functionality). After some research, found that there's a page in Acquia documentation with an explanation of how to install a Drupal module on Acquia Cloud.
The approache I started doing was to develop the application locally using Acquia Dev Desktop, add new modules using local tools like Drush or the Update Manager, and then push the code to Acquia Cloud with Acquia Dev Desktop.
Once the public key was generated, to complete the process I'm redirected to this link. Following it I was able to generate the SSH key which appears under
/app/profile/ssh-keys on my Acquia Cloud account.
After this, I'm in need of a Private key file to continue the process and i'm blocked. Given this information bellow, what can I do to have it?
