### Improving the documentation

Hi,
I found that there is no documentation on the part of using Kyuubi in Apache Superset and I wanted to share it.

### Are you willing to submit PR?

- [X] Yes. I would be willing to submit a PR with guidance from the Kyuubi community to improve.
- [ ] No. I cannot submit a PR at this time.

The issue does not name a documentation file, page, or test. Start by locating the existing BI tools documentation and checking how Apache Superset integrations are documented; done means adding clear guidance for using Kyuubi with Apache Superset.
