I am currently working on Jira Integration for a product in my organisation, and we are developing a package for auto-rendering and auto-populating, and therefore creating a jira ticket automatically.
There may be multiple scenarios/cases for the markdown conversion and we have handled almost all of them. Now we are working on definition terms and definition descriptions rendering, but it seems there's no markdown support for the same.
The following is a screenshot for the markdown syntax for my need, but the same(or any similar syntax) isn't available for jira cloud:

Can anyone confirm whether Atlassian has a support for the same or not, so that we can close the requirement for the moment.
