It should be possible to support running under WSL (v2 at least) for --live option.

• Run whoami.exe to retrieve current user SID

whoami.exe /user /fo csv
"User Name","SID"
"machine\user","S-1-5-21-..."

• Get mounted drives from /proc/mounts with fstype drvfs
• Build the possible recycle bin folders from above data

For detection of WSL environment, probably this comment would be one of the most comprehensive.
