Ignore dir name only in root

Hi,
here is repo structure

dir1/xyz/override/
dir2/
override/

I'm trying to ignore all content of **override/** but not to ignore **dir/xyz/override/**

All my tries failed. My tries list:
(I use dot to target whole repo files)

source: ". ,!override/*"

source: ". ,!./override/*"

source: ". ,!./override/*, ./modules/*/override/*"

source: "./*.*,modules/*,themes/* ,!override/*"

I see no more options to check. If someone know how to deal with it I'll pleased

No source file, test, or entry point is mentioned. Start by reproducing the reported ignore-pattern behavior in the action's file-selection path, then inspect how the listed source patterns are parsed. Done means root-level override/ content is excluded while nested dir1/xyz/override/ content remains included, with a regression test if the repository has coverage for this path.
