I tried create tickets using AnonymousIdentity. I'm using kotliin.

In my application

Zendesk.INSTANCE.init(
    applicationContext, getString(R.string.zendesk_url),
    getString(R.string.zendesk_app_id),
    getString(R.string.zendesk_client_id)
)

Support.INSTANCE.init(Zendesk.INSTANCE)

Then in my activity, I tried to show HelpCenterActivity

Zendesk.INSTANCE.setIdentity(
    AnonymousIdentity.Builder()
        .withEmailIdentifier("email here")
        .build()
)

HelpCenterActivity.builder()
    .show(this@MainActivity)

I also noticed that if I remove the the email identifier it will open and close immediately.

Logcat:
