Offline files do not work

[regisdenice]

In windows explorer (win 7 SP1 x64), the offline files does not work with sshfs-win (but does with samba)

Details:
Given that I installed last versions of sshfs-win 2021.1 Beta2 (sshfs-win-3.7.21011-x64) and WinFsp 2023 (winfsp-2.0.23075)
Given that I am in Windows Explorer in a Linux drive mounted with sshfs-win (\sshfs\me@myserver\home)
When I right click on a file
Then the "make this file available offline" option is not displayed

It works fine with samba folders though
