Is there a way to update a Customer's `multipassIdentifier`?

[NaotoKoshimizu]

Hello, I'm now developing our Headless store with StorefrontAPI and AdminAPI of Shopify Plus.

I read the document about Multipass and implemented the multipass login.

It's almost working correctly, but I found that Shopify Admin API's `customerUpdate` mutation doesn't support updating Customer's `multipassIdentifier`.

Then if the customer's identifier (such as username) was changed, how should I modify it?

Thank you.

Hello NaotoKoshimizu!

Did you solve this problem?

I need to update the multipass_identifier of some of my clients but I can't find how to do it.

Thanks you!
