How to update a extended participant in Hyperledger composer correctly?

Problem:

I have created an extended participant in .cto file in Hyperledger composer. It is like this.

participant User identified by nic{
o String nic 
o -----
o -----
o -----
o String verified
}

participant Seller extends User{
o ----
o ----
}

participant Buyer extends User{
o -----
o -----
}

But now I am pacing a problem. If I update some property of user should I update only user registry or should I have to update all three participant registries? Suppose that I am going to update the verified property of User. I look for a solution to solve this problem on the Internet but I was unable to find any good solution which will solve this problem. Thank you

Since the User participant is linked to Seller and Buyer someway, you don't need to update all others, i think that you just need to do something like:

   const participantRegistry = await getParticipantRegistry(you.org.net.User);
    let user = you.org.net.User#UserToUpdate
    user.verified = true;
      // Update the participant in the participant registry.
    await participantRegistry.update(user);

The same works for update a extended attribute:

     const participantRegistry = await getParticipantRegistry(you.org.net.Seller);
        let seller = you.org.net.Seller#UserToUpdate
        seller.atributteExtended = true;
          // Update the participant in the participant registry.
        await participantRegistry.update(seller);
