Quicker way to open all files in a directory recursively in Helix?

[8ullyMaguire]

I want to open all files under a directory recursively in Helix. For example using:

hx ~/.config/tmux/**/*

fails because it hits directories.

I know I could do:

find ~/.config/tmux -type f -exec hx {} +

but that feels too verbose.

Is there a simpler, quicker way to open all files recursively in Helix?
