VSC Snippets variable transformation using Regex quantifiers i.e. {1,3}

Question

So, I wanna create a snippet that turns e.g. rgba(102,83,47,1) type strings into 102 83 47. I already wrote a working RegEx expression: regexr.com/7mo33

(?:rgba\((\d{1,3}),(\d{1,3}),(\d{1,3}),.*)

Which returns the RGB values into three capture groups.

But my VCS snippet doesn't seem to be working:

    "Vic3araxRGBpickertoPDX": {
        "prefix": [
            "RGB Picker to Clausewitz"
        ],
        "body": [
            "${TM_SELECTED_TEXT/rgba\((\d{1,3}),(\d{1,3}),(\d{1,3}),.*/$1 $2 $3/}"
        ],
        "description": "Removes the rgb() and turns commas into space"
    },

It's simply returning ${TM_SELECTED_TEXT/rgba\((\d{1,3}),(\d{1,3}),(\d{1,3}),.*/ /} My best guess is that the quantifier brackets at \d{1,3} mess with the variable transformer, but I have no idea.

Btw. I'm not married to that RegEx expression, so if there's a better way to do it, I wouldn't mind.

Change your body property to

    "body": [
        "${TM_SELECTED_TEXT/rgba\\((\\d{1,3}),(\\d{1,3}),(\\d{1,3}),.*\\)/$1 $2 $3/}"
    ],
