Problem to solve
The tool can take several seconds to load, and the lack of visual indication makes it impossible to know if something failed, if there are no results, or if the tool is loading.
- Have a "loading" flag — turn it on/off in the state. Have a conditional in the component.
- Display a loading indicator when the tool is loading and generating the supports.
- Use a bootstrap loading indicator for now, we will convert to OOjs UI in T180090
