Recently i tried to install an add on for JIRA and get this error
The add-on you are trying to install is only available for Atlassian Cloud.

I install it by pasting the url atlassian-connect.json hosted by my computer and using ngrok
I can install it through my own JIRA site, however ,when i install it to my company JIRA site , it has that error.
Edit : I think that because my company using JIRA Server which only accept addon built using Plugins2 with jar files... , and i'm using JIRA Cloud.
Is there anyway to convert the addon build for JIRA Cloud to install for JIRA Server
