Migrate TOTP secret key to Okta

I am migrating Grails Spring Security users to Okta. I am able to migrate the BCrypt passwords. I now want to migrate TOTP secret keys. Is it possible to migrate TOTP secret keys to Okta?

Okta supports using a custom TOTP factor and this might be what is needed for your case
