share project not working on sap hcp for native hana development

Hi,

I am trying to do a native hana xs application on hcp.

I am following the steps on the help website and cannot share the project. Getting the error below:

Authorization 'REPO.MAINTAIN_NATIVE_PACKAGES' missing for package 'P1812335007trial.myhanaxs.hello' or one of its parent packages.

I tried to create the project using 'share project in sap repository' but getting the following error:

Operation failed
Repository request failed.
Repository: User is not authorized to execute specified operation;User 'DEV_31QJL56K1Z2MCP3VMP7Q3XDBW' has no authorization, privilege: 'REPO.READ', package: 'hello'!, code: 40,156, argument:
