I'd like to use Clickup as a client-facing portal. Currently, you can share specific dashboards & lists with guests, but I would like to be able to customize a hub where clients can access their files, receive and pay invoices, view a project schedule, have a message center, receive and sign documents, schedule a meeting, and view tasks assigned to them. I have found ways to do a few of these things, but not all, and I would like to be able to have more control over how the guest account is organized. For example- I'd like guests to see a sidebar organized into custom categories (message center, calendar, notifications, invoices, etc.)
