Right, it looks like you don't have permissions to push yet. For more details on how to request commit access after you submitted a few patches, see https://llvm.org/docs/DeveloperPolicy.html#obtaining-commit-access

In the meantime I can commit the patch on your behalf (https://llvm.org/docs/Phabricator.html#committing-someone-s-change-from-phabricator). If you want me to do so, please let me know the name & email I should use to set the author in the commit.
