** suggestion **
Kindly check for typing-extensions>=3.7.4,<5; python_version<"3.9 Here version is not updated as in next versions of python it is not needed, as this PR is more dedicated to area/adk, more construct solution would be to update it to this typing-extensions>=3.7.4,<5.

Requirements in sdk/python/requirements-dev.txt are quite old suggestion is to update them to newer versions.

Hi @jayzalani. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
