Access token from Browser flow

Hi guys, I’m new to Keycloak and I’m trying to implement the browser flow (with some changes to encrypt user’s password, which I have it working) but I need the access token, for consuming the rest of the resources, and I can’t see in any response header something like the access token. So my question is, can I get the access token from the Keycloak browser flow? Or should I create my own login page, and call the API /realms/{{realm}}/protocol/openid-connect/token in order to get it?
Thanks in advance.
