Support for Figma plugins or other Iframe enviroments

Problem

Mixpanel client will not work in Figma plugins UI.

Why?

Electron limitation when Iframe content is loaded as Data-URI. Both localStorage and document.cookie are not available (similar problem).

Mixpanel client has configuration option to switch off persistance disable_persistence, but it won't help, as it accesses cookie, which crashes the client
