**As** a developer integrating op-blocknote-extensions into an external application
**I want** to configure a separate "real OpenProject URL" (distinct from the proxy/API base URL) 

**So that** generated work package links point directly to OpenProject instead of going through the proxy

**Acceptance criteria**

* op-blocknote-extensions allows specifying a Begin of the insertionoptional proxy\_urlEnd of the insertion Begin of the deletion real OpenProject URL separately from the proxy/API base URLEnd of the deletion on initialization Begin of the insertion(alongside the existing base\_url)

* if the proxy url is not given, it is set to the value of the base\_url

* all API requests that need authorization use the proxy\_urlEnd of the insertion
