You can recover deleted assets within 30 days of deleting them.
Each user has access to view assets they themselves have deleted. You cannot view assets deleted by others.
To recover a deleted asset, simply click your profile picture, then choose the "Bin" option:
This will open the bin (a.k.a. trash), where you can view all assets you have deleted in the last 30 days. You can use the Filters panel to narrow down the view by folder or any other field.
To restore an asset, select it using the tick box on the thumbnail, and click the Restore button. You can also select multiple assets, or click "Restore all" to restore all assets in the Bin.
