Hi @rahmat,
If you need this feature to be active, you should request the 10 PNGOs to create an account in KoBoToolbox. Else they should not be able to use this feature.
If and in-case you do not want to use this feature you still have an alternative (but it would take a lot of your time to mange the project data). The workaround is that you will need to deploy the survey with 10 different names and share it to them separately. If you do this one PNGO will not be able to see the data of other PNGOs. You could then merge the dataset manually once the data collection is over. To provide access to the PNGOs to view the data entry status and provide access to the dataset you could follow the instructions outlined in the post that has been discussed earlier here:
Have a great day!
