With SlackBridge, can a user claim account their cloned account?

If an online community has Slack and then starts using RocketChat via SlackBridge, I understand from the docs that a new RocketChat user is created for each Slack user, in any Slack channel where the SlackBridge bot is invited.

Is it possible for a Slack user to claim the cloned Rocket Chat user account or vice versa?

This would prevent people from having to check 1-1 messages in both services at the same time.

Thank you!

Does anyone know where I can find the answer to this one?

Thank you!
