TLS version logs - Worker

Hi colleagues! I have a question.

One of our clients is using a Worker which excludes a list of IPs so they can access the application using TLS 1.0 and TLS 1.1. Our client wants to know if it’s possible and how to see which of these IPs are still accessing their application using these weak versions of TLS - 1.0 and 1.1 so they can send them an email and tell them they will upgrade the TLS version to higher to secure their systems more.
The list of the IPs in the Worker has about 500 IPs if this information has any value for the main question.

Thanks in advance!
