I had developed a Kibana plugin for Kibana 5.5.2, and now I want to use it in Kibana 7.6. It is a simple application that reads and writes some data from/to the ES "server" but it was created as a Kibana plugin because we make use of some visualizations provided.
My main question is: can I still use Angular for the plugin, or will I have to use React (therefore I will have to rewrite the UI)?
And, if yes, will I still be able to use Angular in Kibana 8? Because I see that several things regarding plugins will change in Kibana 8.
