GitHub Roots Radicle repository access

We are an agency and we bought a license of Radicle but only the user who made the purchase have access to the Roots Radicle repository (
Is there a way to invite more users to be able to add/track issues?

Welcome and thank you for purchasing a Radicle license!

Only a single user having access to the repo is supported at this time. Team licensing pricing may be introduced in the future, and it would allow you to allocate additional repo invites to team members.
