What trigger would change an issue status in JIRA when it gets merged to a specific branch in Github

[Olga Buslovich]

We've tried the following trigger in JIRA flow settings (see attached) but it triggers the Status change in JIRAs for any merge e.g. merging to a DEV branch.

But what we really want is to get the status set to QA only when the JIRAs that are part of release candidate are checked in and merged to the QA Branch (ONLY!) in Github.

Any suggestions on how to set this up in JIRA (via a trigger or an automation rule ) that would move the release candidate tickets to QA when they merged to the QA Branch in Github. THA, Olga
