HANA Cloud schema is not showing in HANA Studio

Hi Experts,

                 I have created a HANA DB Instance called "kowshikhana" on the HANA trial cloud platform. I could see that a DB schema called "kowshikhana" is also created automatically. Please view the first attachment.

I opened HANA studio and connected to the cloud HANA instance "kowshikhana". I could see a lot of catalog objects. But not the schema "kowshikhana". Please view the next attachment.

Please let me know:

1) Why is schema "kowshikhana" not showing up in the HANA studio, even though I could see it on my cloud account?

2) What's the purpose for the other schemas that starts with "DEV_" or "NEO_"? Why has SAP created them automatically?

Regards,

Kowshik
