Question about Rise 360 with embedded Storyline blocks

If I choose to embed a Storyline 360 slide into a Rise 360 course, how is the Storyline 360 slide saved to the course? I noticed that to embed a SL slide you first need to publish it to Review 360.

Is the SL slide exported into the course that Rise 360 will produce for me to host on for example ScormCLOUD or is it hosted from the cloud that serves for Review 360? I don't want to depend on several hosts for my courses to work, I want it all hosted on ScormCLOUD and I want my courses to still work even if we decide to go with another software in the future and not renew with Articulate.
