Help with hyprland workspace configuration

[poseidon-rises]

I want to configure my workspace so that the active workspace has brackets (ex not active is Λ, active is [Λ]). I have this configuration but I'm not sure how to do what I want to do:

"hyprland/workspaces": {
  "disable-scroll": false,
  "all-outputs": true,
  "warp-on-scroll": false,
  "format": "{icon}",
  "format-icons": {
    "active": "[ ]",
    "1": "Λ",
    "2": "β",
    "3": "ζ",
    "4": "Δ",
    "5": "λ",
    "6": "Φ",
    "7": "Ξ",
    "8": "π",
    "9": "Γ",
    "0": "Ω",
    "default": "ξ"
  }
}

Try this:
"format" : "[{id}]".

If it doesn't solve the issue, you can just create 2 separate modules and in the first one in the format there will be '[' and in the second one the ']' and put the hyprland/workspaces between them like that:

"modules-center"["custom/open", "hyprland/workspaces","custom/close"],
"custom/open"{
"format": "["
},
"hyprland/workspaces":{
  "disable-scroll": false,
  "all-outputs": true,
  "warp-on-scroll": false,
  "format": "{icon}",
  "format-icons": {
    "active": "[ ]",
    "1": "Λ",
    "2": "β",
    "3": "ζ",
    "4": "Δ",
    "5": "λ",
    "6": "Φ",
    "7": "Ξ",
    "8": "π",
    "9": "Γ",
    "0": "Ω",
    "default": "ξ"
  },
"custom/close":{
"format":"]"
}
