Install Kibana plugin in Elastic Cloud

Hi

I am evaluating an Elastic Cloud instance

I want to make a video player plugin for Kibana - I found a guide for isntallation but it's talking about putting the plugin in a folder... and I don't have terminal access to the Elastic instance (Kibana plugins | Kibana Guide [8.15] | Elastic)

How do I install a plugin to Elastic Cloud?

It's not supported. See Add plugins and extensions | Elasticsearch Service Documentation | Elastic

Plugins are not supported for Kibana. To learn more, check Restrictions for Elasticsearch and Kibana plugins.
