Hi @shaista_karim!
(Nice to see you on the forum!)
It looks like this is my bad, the import tool is missing in the docker container. I will get that fixed and let you know how to proceed with updating it once it's ready. We're actually about to have another release, so if you are able to wait a few days, you can update to the latest version in a single step.
If you aren't in a huge rush, I might advise waiting until next week to update.
