Add an option to delete failed generation records and clear prompt history.

Currently, Adobe Firefly (Web version) lacks an effective way to manage or delete "failed generation" records. While successful images can be managed in "Your Stuff," failed prompts and blank placeholders resulting from errors remain in the history with no option to remove them.

Furthermore, there is no manual option to clear the prompt history/suggestions in the input field. I suggest adding:

1. A way to "Delete failed attempts" from the generation history.

2. A feature to clear or manage the prompt history in the input field.
