Perfetto UI currently supports an embedded mode via a URL parameter. This suppresses the sidebar and other default behaviours of the UI. However, I am building an application whose integration needs go deeper than this. In particular, I need to be able to

• adjust the way routing works because my application uses the URL hash already for its own purposes
• I need to tweak the content security policy
• I need to customize the keys used by CacheManager for caching in the browser, to separate the caches from my application and satisfy other restrictions
• allow file CORS origins
• my application loads up traces into the trace processor before initializing the Perfetto UI, so I need to suppress the dialog that prompts to open a trace already loaded
• handle uncaught errors and promise rejections in my application
• and possibly more

So some kind of API by which I can inject customizations of these Perfetto UI behaviours, before initializing the UI app, would be most helpful to my application.
