Making prefix remap work with whichkey (e.g. remapping C-w to <leader>w)

[tvsfx]

Is there a way to make whichkey work out of the box when remapping a prefix key?
For example, in my case I am remapping C-w to <leader>w for window navigation. If I just set vim.keymap.set("n", "<leader>w", "<C-w>") in my config, then the built-in whichkey maps for C-w do not pop up when pressing <leader>w. My current workaround is to just recreate each mapping manually. I thought perhaps it might be a matter of setting the right trigger (adding { "<c-w>", mode = "n" } to triggers), but I've had no luck getting this to work.
