Several Slack applications (e.g. Twitter, Google Calendar) provide a configuration page after installation on Slack. However, this seam feature is only available to Slack commercial partners, and not as a standard feature for every application developer.
Developers must implement this themselves using an external / script application that is connected to the Slack application and stores the configurations in its own database.

Looking at the official Slack Plattform Roadmap for developers , this feature can be implemented in the future in the section “Installing applications from Slack”.
