Does the "Autoprovision Roles for All Users" job delete manually assigned roles? (Service CX)

Hi team,

We want to better understand the behavior of the "Autoprovision Roles for All Users" job.
When it runs, does this process affect roles that have been manually assigned to users? Specifically, does it delete them or keep them as is?
We are implementing Service CX's Internal Help Desk.

Thank you for your help.
