Enable Session in SharePoint 2019

Question

I need to enable session state in SharePoint 2019, I already have many web parts which I need to consume session but I got this error

Application error when access /_layouts/15/employee.aspx, 
Error=Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive.

Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \ section in the application configuration.

I have a SharePoint 2019 farm with 4 servers! and I need to know where exactly should I enable session state in SharePoint 2019?
