    - This option is relevant only when `persistTokens` is true.
    - The session token cookie is set as a [`Secure`](https://datatracker.ietf.org/doc/html/rfc6265#section-5.2.5) cookie. It will be sent only over HTTPS connections.
In addition, some browsers (e.g. Safari) may not store `Secure` cookie if the hosted page is running on an HTTP protocol.
    - If the cookie domain set on Descope configuration doesn't match, or is not a parent domain of the current domain, The cookie will be stored on the current domain that runs the code. Examples:
     - Project cookie domain is acme.com, current domain is app.acme.com - the domain will be set to app.acme.com
     - Project cookie domain is acme.com, current domain is my-app.com - the domain will be set to my-app.com
