Customizing button labels in JIRA Service Desk

[Chethan S.]

We are in the process of migrating from Jira 6.3.14/JIRA Service Desk 2.3.6 to the latest versions available. In the older setup, we had used the add-on "InProduct translation for JIRA" to translate certain items in the interface. 

Some examples are - 

1. "Share with Customer" button in comment field reads as "Respond to Product Request Creator" 
2. "Requests" - that lists all the requests a user has placed is shown as "My PRs"
3. "Shared With" in customer portal shown as "People Involved" etc.

Already tried - 

1. Atlassian Support suggested us to edit the language pack but interestingly there's no language pack delivered for the English language in JIRA Service Desk. They confirmed it once I replied stating I couldn't find the files. Then they suggested seeking support from the community since this kind of procedures aren't supported.  
2. Deviniti's add-on Translation for Jira Service Desk doesn't seem to work for same language translations.

What are our options?

You can put <script> elements inside the Announcement Banner to modify HTML elements.

For example this snippet will hide the "Share With Customer" button on a JSD comment

<script>
const thisWindowURL = window.location.href
if(thisWindowURL.indexOf("PROJECT_KEY") >= 0) { document.write("<style>button.aui-button.aui-button-primary.sd-external-submit {display:none}</style>"); }
</script>
