The app uses Gitlab access tokens to clone repositories for scanning
To setup a access token go to your GitLab project->Settings->Access Tokens
Use an appropriate expiry date for your token
The minimum role required is Developer and the minimum scope is read_repository
Access tokens can be created for GitLab Groups as well which allows you to use a single access token for a group of projects / repositories (learn more)
Remember to copy / store the access token for use later when configuring the app server
