How to backup all settings and restore using SSH script

I’m running postman as a snap on a Ubuntu based Linux distro (elementaryOS).

When I export the data in the settings dialog, it is missing the settings I made

  • custom proxy
  • dark theme
  • SSL certificate validation = off.

The dump I get looks like this

{
	"version": 1,
	"collections": [],
	"environments": [
		{
			"id": "5859c101-8d67-4293-a093-05c265dbed70",
			"name": "My Workspace - globals",
			"values": []
		}
	],
	"headerPresets": [],
	"globals": []
}

I want to backup my settings to a Git repository where I also have my setup scripts.
How to do it so that all settings get persisted?
