[Charts / Canvas / Streamlit] lock feature to prevent accidental deletion

In Charts and Canvas and Streamlit, items created for quick checks or simple testing (which are not valuable and can be deleted without issue) are listed together with highly valuable items used in daily operations (which would cause problems if deleted).
Although only the creator can delete their own items, as CDF usage grows and more Charts and Canvas assets are created, the risk of accidentally deleting important items increases.
To prevent this, could we have an optional deletion lock feature for Charts and Canvas and Streamlit?
When the lock is enabled, the item cannot be deleted; once the lock is manually removed, deletion becomes possible again.
This would help protect important items from accidental removal.
