Problem with id generation in mongodb

https://github.com/doppelganger113/example-go-tui/blob/236f8d7dc91573b78cf61cd1b5ad3de0a53d59a0/internal/storage/user_repository.go#L13

Love your blog post, found it very helpful yet i run into this problem where it leads to id duplicates in mongo. Nothing really related to tui itself, but maybe helpful for someone who wants to strictly follow the post.
Following a simple solution.

`type User struct {
Id primitive.ObjectID `bson:"_id,omitempty"`
Email string
}`
