I have a website A (with his own domain) and another website B (on another domain). When a user enter to website A a banner is displayed allowing him to accept/reject cookie. If he accept we enable the use of datadog rum.
Then the user can be redirected to my other website B in order to perform other actions.
I'm watching datadog documentation : https://docs.datadoghq.com/fr/real_user_monitoring/browser/
useCrossSiteSessionCookie
Optional
Type: Boolean
Default:false
Use a secure cross-site session cookie. This allows the RUM Browser SDK to run when the site is loaded from another one (iframe). Implies useSecureSessionCookie.
I'm wondering if I could use useCrossSiteSessionCookie parameter to use datadog rum on the website B without re asking user to accept cookie ? Or is it only possible with iframe ? Because I do not know how to make it work :(
If it's not possible do you know other solution to my issue ?
