Regex to substitute " " to "_" in automation function RegexReplace. \s not working.

[Pico]

Hi all,

while creating my automations, I need to use the regex replace 

The filed I have is like "my_string" and I need to convert it to "my string" , with a space instead of the "_" .

If I use "\s" it doesn't work, neither inserting only the space in the box, nor [' '].

How can I do it?

thank you very much!

It seems like it uses regex to find the value to remove, but not for the new value to insert.
