A cookie associated with a cross-site resource at https://example.com/ was set without the SameSite attribute. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with SameSite=None and Secure. You can review cookies in developer tools under Application>Storage>Cookies and see more details at https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032.
Please let me know how to set the SameSite cookie attribute. Thanks in advance.

SameSite=None requires Secure The warning appears because any cookie that requests SameSite=None but is not marked Secure will be rejected. To fix this, you will have to add the Secure attribute to your SameSite=None cookies. A Secure cookie is only sent to the server with an encrypted request over the HTTPS protocol.
A New Model for Cookie Security and Transparency Developers must use a new cookie setting, SameSite=None , to designate cookies for cross-site access. When the SameSite=None attribute is present, an additional Secure attribute must be used so cross-site cookies can only be accessed over HTTPS connections.
Resolve this issue by updating the attributes of the cookie: Specify SameSite=None and Secure if the cookie is intended to be set in cross-site contexts. Note that only cookies sent over HTTPS may use the Secure attribute.
You can add SameSite cookie attributes in the set-cookie HTTP response header to restricts browser behavior. It may prevent the browser from sending the cookie's key=value pair based on the type of interaction that triggered the HTTP request.
In Rails 6.0 and 6.1 the same_site attribute has been added:
cookies["foo"] = {
value: "bar",
secure: Rails.application.config.secure_cookies,
same_site: "None"
}
For Rails 5.x and lower, the rails_same_site_cookie gem is a good option for adding SameSite=None; to all your app's cookies. It uses middleware to do it.
