How can I get firebase verify email OOB code?

https://firebase.google.com/docs/reference/rest/auth#section-send-email-verification

Can I get the OOB code On a label when a verify email is sent?

It is not clear from the documentatioin as to how you return an oobCode (although one of the methods does show the use of the oobCode / [VERIFICATION CODE], but you can check the user’s data to see if they have verified their email address.

I can get the OOB code if I have sent a verification email.
Is that possible?
Or is an OOB code a User ID token or an Id token?

I do not believe you can

oobCode and user/ID Token are different things
