Understanding Session information

I want to understand the session information ( which are highlighted in yellow ) as shown below:

Session(Test Employees,2,1633105546513,Map(gatling.http.cache.baseUrl → XXX, email → XXX , gatling.http.cache.dns → io.gat
ling.http.cache.DnsCacheSupport$$anon$1@5bd98072, uuidEmployee → XXX , nom → XXX , gatling.http.ssl.sslContexts →

Please I need response ASAP
Thanks in advance

The actual session content is an implementation detail.

Thanks Stephane for your response, you can explain more please

Some data in the Session is for internal use, which is what you see here. This data is subject to change anytime. I fail to see a reason for you to investigate this.
