Login without input url

Hi everyone! How are you doing? I recently cloned the Android repository of Nextcloud (https://github.com/nextcloud/android ) and currently, by default, when I try to log in through the app, I need to enter a URL (which in this case is the sharing URL of my account). After inserting the link, I get redirected to the web where I authenticate with my username and password. What I’d like to know is if anyone has already done something similar or knows which path I should follow, because my goal is that when I open the application, I only need to enter my username and password, and it authenticates with the platform directly inside the app, without redirecting me. Not only with my own user, but also for example being able to log in with different users as if the sharing URL pointed to the platform instead of being tied to a specific account — does that make sense? Another point I’d like to mention is that I’m running Nextcloud locally inside a container with image version 30.0.14. Does anyone know how I can achieve this?
