Hello, Good day. You have two options. Create a filter with JQL to find the issues nearing due date and subscribe to the filter for notification. https://support.atlassian.com/jira-software-cloud/docs/manage-filters/

Or you can use automation to send notification for same JQL.

assignee = currentuser() and due date >= 2d
