We are building a new application based on constellation (cosmos-react) in 8.8.2 version. When trying to create a new landing page, there are only 4 out of the box widgets available. If we want to create our own custom widgets, do we have to create a react component or is there any other way? I tried creating a section (dashboard widget) via dev studio, but this is not appearing when I go back to app studio in the landing pages. We have to provider user with simple 'Search' screen with specific criteria and invoke api call (pull data from external system) upon clicking on the search button and fetch results. We don't want to provide this via case type rules, as there are no updates involved.

Any suggestions would be appreciated!
