Which other fields can be changed in import external project (Jira-software ) using JSON file?

Question

I am using Jira server in local test instance. Copy, pasting the JSON example from Importing data from JSON  and making changes to few user related and links fields, I can see a project created with Project > Import external project > JSON > upload file.

In checking Project setting > Summary page, I can see I have made changes to versions, components, users and even issues are created.

But I need to change issuetypes, priorities, workflows, fields, screens.
Are these modifiable using JSON? Can anyone include example of it?
Or changing it in UI is the only solution?

Thank you, I didnot know that.
Is it same if I use other file format too like csv?
If other file formats are not the options, then I can change issue type, workflow, fields and screens using either UI/Rest API, is it?

Issue type, workflow, fields and screens are not fields, so their values cannot be changed by issue imports.
