DigitalOcean Apps, Laravel scheduler

I found this thread in DO's support community: https://www.digitalocean.com/community/questions/cron-jobs-for-app-platform

However, as I write there, I have still not managed to set up such a worker for Laravel cronjobs/scheduled tasks in DigitalOceans new "Apps". My solution so far is manually hosting a droplet for this purpose, which I then have to manually update.

It seems as the problem is, that the worker cannot access NPM repositories online and I have no clue how to disable npm install, and I'm sure if I did that, then composer install would suffer after.

Have any of you managed to get this working?
