## Screenshots / GIFs
<!--
We have screenshot tests in the project, so attaching screenshots to a PR is not mandatory, as far as there
is a Composable Preview covering the changes. In this case, the change will appear in the file diff.
Note that all the UI composables should be covered by a Composable Preview.
Providing a video of the change is still very useful for the reviewer and for the history of the project.
You can use a table like this to show screenshots comparison.
