Unable to access configure page for Adobe XD plugin in Jira

The configure page for Adobe XD is greyed out and not accessible in Jira. Due to this we are unable to add/remove projects in Jira.
Please find the attachment of screen for reference

This sounds like you’re trying to get support for the integration in JIRA. This forum is for development of plugins, not support. I’m asking internally for the best place to ask this type of question.

Can you please help us on this issue, where we can post this?
Thanks in advance
