Hi,

In the Add Repo dialog, click Clone remote Git repo and enter the repository URL. Select your Git provider from the drop-down menu, optionally change the name to use for the Databricks repo, and click Create. The contents of the remote repository are cloned to the Databricks repo.

Please refer: https://docs.databricks.com/repos/work-with-notebooks-other-files.html#clone-a-remote-git-repository

Please let us know if you need further clarification on the same.
