You can find workflow in "Project Setting" -> "Request types" -> "Edit workflow". But I cannot see an export option for it. (For classic project template, the workflow can be see in Jira setting)
I have checked this page https://support.atlassian.com/jira-service-desk-cloud/docs/manage-how-work-flows-in-your-next-gen-service-desk/, and cannot find useful inforamation about export request types. We can copy a workflow of one request work to another, but it cannot be done across different project.
Hello @V Z and welcome to the community!
The option to copy next-gen project configurations and workflows wont be available until later this year. This is announced in the link below.
Does this answer your question?
