How to increase per user storage allocation?

I just installed NextCloud on my personal server. Each user appears to have 170GB at the moment. How can I increase this limit?

When logged as Admin user, click in your name (top right corner), then Users, click on “pencil” to edit, and change default value in the storage column (usually “blank” AFAIK) to any value you wanted to asing to individual users.
