Don't work for guest (null) users

[4n70w4]

Hi! I use https://github.com/jrseliga/pseudo for able guest users with null id.

But don't work send notifications to guest users:

Illuminate/Database/QueryException with message 'SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'notifiable_id' cannot be null (SQL: insert into `notifications` (`id`, `type`, `data`, `read_at`, `notifiable_id`, `notifiable_type`, `updated_at`, `created_at`) values (28d892ed-dfcf-4603-aeb2-ab9fa35c93b9, App/Notifications/TestNotification, {"level":"info","message":"Test message","url":"https:////coreproc.com","target":"_self"}, ?, ?, Pseudo/Auth/Guest, 2021-01-11 09:01:13, 2021-01-11 09:01:13))'

I manually alter table and change to nullable. Message saved to table but realtime pushes don't work.
