Join events from multiple Datadog RUM instances on different pages under the same domain by session

[lz000]

What are you trying to achieve and what is your issue? Please describe.
We have 2 pages
https://www.example.com/page1
https://www.example.com/page2

Each page has a different datadog configurations with different app ids
datadogRum.init({ applicationId: 'app1id' }) on page1
datadogRum.init({ applicationId: 'app2id' }) on page2

Both pages will fire events using addAction. Do the events fired from both pages share the same session? Can I replay user's interaction both pages within the session?
