After reviewing the tasks, you can Sync them to your CRM using this button referenced in the screenshot below. If you need to create a task manually first, you can click "Add Task" below the generated tasks and add it in.
In the Sync window, you can reassign tasks to your teammates by clicking the name of the preselected assignee, change task type via the dropdown on the left (depending on your CRM, these can include Case or Workflow) and make any other changes to the tasks before you sync them over.
Once you've made your selection in the Related to box regarding who you're going to relate these tasks to, you are ready to sync the tasks to your CRM.
After tasks are synced to your CRM, they have a "Synced" status and become mostly read-only, though you can delete them from Jump and then they will only exist in your CRM.
