Hi @Shekharrajak,

Instead of binding to a specific Flink version, I think Flink Agents should support multiple Flink versions at the same time. Not saying any Flink version should be supported, but we should at least allow users to choose from the latest and LTS ones.

@GreatEugenius is currently investigating the possibility of multi-version flink support. If it works, we'll create issues and start work on it.
