There could be times where some sensitive data could be inadvertently added to an issue in a text format, on a comment, description, or other forms (Fields, etc). For security reasons and due to regulations (GDPR and others), this information needs to be removed from the instance. Although the user can remove the text, the information will still be present on the history and activity tab of the issue.

Since the history tab can't be disabled (JRACLOUD-67300), Would be useful, and at some point necessary, that the administrators have the ability to remove data from the history or activity tab in case they need to hide sensitive information from the instance. This would also remove the information on the activity stream where users can see all the changes.
