visitor- can't share the stores

edit

If a guest wants to open a pattern in read-only mode, the share owner should grant the guest access to the store but uncheck the "Edit", "Add", and "Delete" rights for the user. Moreover, the owner should also set the guest as a member. When the guest opens the owner's file, please remember to choose the owner's share name in the upper-left corner before opening.

that is what i do in the setting, here the screenshot for your ref.
