searching an External user in People picker and starting an invitation

Question

I would like to know, how can I search for non-existing external users and sending them an email like the picture bellow

Below is the code that I have used:

   <PeoplePicker
        context={porps.context as any}
        personSelectionLimit={3}
        groupName={""}
        onChange={_addUser}
        principalTypes={[PrincipalType.User, PrincipalType.SecurityGroup]}
        resolveDelay={200}
        defaultSelectedUsers={_Picker}
       
      />
