How to add custom ChannelType LOVs for Interactions?

Due to the unavailability of the Call Report feature in the Redwood theme, we're transitioning Call Reports to Interactions. As part of this process, we've disabled "Create Call Report" and enabled "Log an Interaction" across all modules in both the CX Mobile App and NGS. While migrating existing call reports, we've noticed that there are only four predefined channel types (Other, Social, Web, and Web Conference) for interactions. However, we have various activity types such as meetings, calls, CEU, follow-ups, emails, special orders, visits, and demos. We need a way to incorporate these additional activity types into the ChannelType LOVs
