JIRA issue assign me option and comment box not showing

Sir, I’ve started working seriously on OpenMRS and exploring JIRA issues. I can see several issues marked as unassigned and incomplete, and I’m interested in picking one to contribute. However, when I open an issue, I don’t see any option to assign it to myself or request assignment via comments. Could you please guide me on the correct process to request an issue so I can start working on it properly?

#give me the proper instruction how to find the issues ,and how to request to assign and where to assign.

If you haven’t requested access to Jira and the Wiki via the helpdesk, that’s the first step. If you have, it doesn’t look like you’re logged into you’re OpenMRS account on Jira. You’ll only be able to comment on or assign yourself tickets when logged in to your @id.openmrs.org account.
