I have installed commerce 9.0 update 2 and my IIS show me the below websites created

What are the certificates associated with each of them?

I do see SitecoreIdentityServer and all other website assigned by default with Sitecore commerce services SSL certificate(localhost) after installation.

Why Identity server certificate exist? Moreover I do see the thumbprint of Identity server assigned on the SitecoreIdentityServer appsettings.json but the certificates is not assigned to it or any websites.

We also create Sitecore commerce engine connect certificate but that is also not assigned to any of the bindings of any of the websites.
