[Question] Share/add cookies to cookie request headers?

**Describe the bug**

I am able to see non-whitelisted headers but I'm only see `bearer-token` for example. Cookies are always override.

It feels like chrome custom tab is blocking our cookies sent with extra-headers.
I am using the example code with our domain that is validating correctly the digital asset links for relation use as origin.

On requests headers I can see bearer-token correctly but cookie has other stuff and does not contain the ones I'm sending.

Is there a chance that we cannot override/add more cookies sent by the server, from the app?

Like if we already have `cookie: "something=123;"` we cannot add (or override) cookies from the app and end up with something like `cookie: "something=123; sendFromApp=newCookie;" `?
