ERX: Expand Mask Selection

Please add the ability to expand an existing mask by a specified number of pixels in Lightroom Classic, similar to the Expand option in Photoshop.

This would allow users to slightly enlarge a mask to refine edge coverage without manually brushing around the selection.

It would be very useful if this feature were available for all mask types in Lightroom Classic.

Appreciate your consideration.
