Not working with tmux-prefix-highlight

[soulomoon]

steps to reproduce
install tmux-prefix-highlight tmux-power-power-theme
set config:

            set -g @tmux_power_prefix_highlight_pos 'LR'

Nothing shows up if I press prefix .0-0

I am using the latest master branch for both

m-prefix-highlight = pkgs.tmuxPlugins.mkTmuxPlugin {
    pluginName = "prefix-highlight";
    src = pkgs.fetchFromGitHub {
      owner = "tmux-plugins";
      repo = "tmux-prefix-highlight";
      rev = "15acc6172300bc2eb13c81718dc53da6ae69de4f";
      sha256 = "08rkflfnynxgv2s26b33l199h6xcqdfmlqbyqa1wkw7h85br3dgl";
    };
  };

m-power-theme = pkgs.tmuxPlugins.mkTmuxPlugin {
    pluginName = "power";
    rtpFilePath = "tmux-power.tmux";
    src = pkgs.fetchFromGitHub {
      owner = "wfxr";
      repo = "tmux-power";
      rev = "2a9a4d19df170c7744ccadeacf0c254444e058fa";
      sha256 = "17p3qf9cmcfx6lldqvn61a6m0kfzfb1aiwg6bvxiyh14nl50z1zn";
