Hey Mehdi,
Welcome to the Atlassian Community! We support Atlassian products like Jira, Confluence, Bitbucket, and Trello. I think your question is about Onos (which is not an Atlassian product). Looks like Onos has a community on Slack you might be able to use for help. Give it a try!
Cheers,
Daniel | Atlassian Support
