How to connect to one of multiple HDI containers (in BTP) of single tenant using CDS

I am referring to URL:

https://cap.cloud.sap/docs/node.js/services

Please get back to me on the following feedback:

• In BTP we have single tenant with multiple HDI containers
• We have a node js application running outside BTP in K8S
• How do we get a transaction for a specific HDI Container from Node js, when the tenant has multiple HDI containers.
