How to import Trello card data and map it to Gitlab issues

As a project manager using GitLab for the first time, I am looking to migrate the data on my Trello board, i.e. from each card to Gitlab and map the card detail to the format of GitLab epics or issues. I am using an organization-managed version of GitLab. I’d like to relay these steps to a developer to assist with the export and import.
