:open command with %sh{} to open multiple files

[Direwolfesp]

Hello!

Problem

im trying to open multiple filepaths that are contained in a txt file with:
:o %sh{paste -sd ' ' /tmp/unique-file} which will output a string with space separated paths like: "/path/file1.txt /path/file2.txt /path/fileN.txt".

However, it just tries to open it as a single string, instead of spliting by spaces to open all the files.

Additionally

Im using nushell and I tried multiple ways to do it. If I type in the shell hx ...(open /tmp/unique-file | lines), It will work as each path will be its own string, however i couldn't replicate it while inside helix with :o %sh{open /tmp/unique-file | lines | str join (char space) } as it will be treated as a single string.

Is there a way I could get around this?
Thanks!
