Is there any way to bind ; as :?

[grindarius]

I wanted to try out helix. I come from NvChad and I wonder if there is any way to rebind ; as :? I have tried

[keys.normal]
";" = ":"

I got error

Bad config: TOML parse error at line 17, column 7
   |
17 | ";" = ":"
   |       ^^^
No TypableCommand named ':'

Press <ENTER> to continue with default config

Is there anyway to achieve what I tried to do? Thank you for the help.

Nevermind I have to just write

[keys.normal]
";" = "command_mode"
