Custom firebase header

[machmielewski]

Hi,

I did some research on the internet and didn't found the answer. Is there any possibility to add custom header which I can obtain in firebase auth header?

I found this: https://firebase.google.com/docs/auth/admin/create-custom-tokens#create_custom_tokens_using_the_firebase_admin_sdk

But have no clue how to inject this in my app.
