Description of the issue:
Hi there,
When I visit https://bitmovin.com/demos/drm using Brave apk downloaded from Google Play, the site tells me that this browser supports Widevine DRM.
But when I build it myself, it does not support Widevine .

I would appreciate it if anyone could tell me how to enable Widevine in Brave apk?

How can this issue be reproduced?

1. Build from source code using “ninja -C out/Default chrome_public_apk”
2. Install the apk I built
3. Visit https://bitmovin.com/demos/drm

Expected result:
The site detects Widevine DRM

Brave Version( check About Brave):
Built by myself, synced the code at Dec.17 2019

Mobile Device details
Device integrated Widevine L1.
Brave app from Google Play is OK

You will need to sign Widevine component for making it work in builds. Local builds wont work because the component isn’t signed when building the apk’s
