Help with cursor shape using tmux

[rEnr3n]

.config/helix/config.toml

[editor.cursor-shape]
insert = "bar"
normal = "block"
select = "underline"

I'm having issues with helix inside tmux. If I don't add terminal-overrides in tmux, my terminal would get a block cursor upon exiting helix. That's not what I've set for my terminal; I've set it to use bar. So I had to add terminal-overrides.

.config/tmux/tmux.conf

set -ga terminal-overrides ",alacritty:Ss=\e[0 q:Se=\e[0 q"

Now I have a different problem. The insert and normal mode works ok except for the select mode. Select mode shows a bar instead of underline. Exiting helix returns the cursor to bar which is what I want. I have tried multiple combinations for terminal-overrides and I'm at a loss.
