how to have multiple themes

[gituser23234235234887]

Hi. I dont know how to have multiple themes in themes.json

{
    "label": "Ghostly Mist",
    "light": {
        "fg": "#999999",
        "bg": "#cccccc",
        "link": "#666666"
    },
    "dark": {
        "fg": "#666666",
        "bg": "#333333",
        "link": "#777777"
    }
}

above works for one theme but I do not know how to edit it to use two or more themes.
EDIT: ok you can ignore what I wrote before.
I figured it out.
you need a different json file for each theme. I find this questionable why we cant just have one big json file with one long list but I guess this makes it easier to share themes like how it is done with vim.
use this link for refrence.
