Setting cookies in selenium webdriver C# for chrome

Question

Does anyone know how to set the expiry date for a cookie using Selenium C# and why an extra character is added to the domain specified?

Any issues with Chrome? And is there a desired capabilities or user preference to be added?

cookie1Dictionary.Add("domain","somesite.com ")
cookie1Dictionary.Add("path", "/");
cookie1Dictionary.Add("expiry", expirationdate.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss.fff'Z'"));            

For some reason the expiry data is null after using the call to

driver.Manage().AllCookies.AddCookie(cookie1Dictionary);

I'm trying to bypass sso login....

So expiry is null and the domain is displayed as .somesites.com it's adding an additional character

I expected to add the cookies with all data specified.

There are the following overloaded constructors for Cookie :

public Cookie(string name, string value)
public Cookie(string name, string value, string path)
public Cookie(string name, string value, string path, DateTime? expiry)
public Cookie(string name, string value, string domain, string path, DateTime? expiry)
public Cookie(string name, string value, string domain, string path, DateTime? expiry, bool secure, bool isHttpOnly, string sameSite)

One way to add a cookie with selenium webdriver is the following:

Cookie cookie = new (name: "key",
                     value: "value",
                     domain: "stackoverflow.com",
                     path: "/",
                     expiry: DateTime.Today.AddDays(1),
                     secure: true,
                     isHttpOnly: true,
                     sameSite: "Strict");

driver.Manage().Cookies.AddCookie(cookie);

with this snippet you will get this output:
