How to get a request header value on an Angular Component?

I have two applications, the first one is Angular and will receive a get request with a value in the header request. This request will be sent by the second application (a chromiumwebbrowser inside windows forms, to use the angular component built-in). My question is, how can I get the value of a header property when my angular components is started? I know I can pass the values using a query parameter, in the url and get it using the routes, but I'm trying to use the headers to avoid security issues and don't expose the value.

Solution

After the MikeOne explanation, I thinked about this, so I solved using a query parameter in the url and getting it using the routes.
