PnP People Picker can't find Guest Users

[jnr-O365]

Hello - I'm using peoplepicker @pnp/spfx-controls-react/lib/PeoplePicker. We have fairly large number of Guest Type users. And I thought peoplepicker would find these users as well. But that isn't the case. Is there any setting which will allow peoplepicker to find Guest type users ? 

Thank you for your time !

This post is two months old, but I came across it while researching something tangentially related and could readily answer it because of that research.@jnr-O365:

Set-SPOTenant -ShowPeoplePickerSuggestionsForGuestUsers $true

or

Set-PnPTenant -ShowPeoplePickerSuggestionsForGuestUsers $true

The description of the "ShowPeoplePickerSuggestionsForGuestUsers" command switch for the Set-SPOTenant version describes its function as: To enable the option to search for existing guest users at Tenant Level, set this parameter to $true.
