How to send email to the respective assignees with their issues crossing due date in Jira Data cente

[Usha B S]

Is there any way to send the mail to the assignee with their assigned issues only. We tried creating A4J rule. But now the rule which we have created is sending all the issues to all the assignees. Suppose if we have 20 issues for the JQL used in the the lookupissues and out of 20 issues 5 are assigned to X person and 3 are assigned to Y person etc. Then X person should receive mail with only assigned 5 issues details and Y person should receive mail with assigned 3 issues details only. This can be achieved if we have some function to iterate based on assignee, like For loop, Advance branching in Jira cloud.

Also let us know if this can be implemented by any other approach apart from A4J rules.
