Cannot get how to enable "download from the Internet" button

[belonesox]

I see, that my "download from the Internet" button is disabled ...

... and I cannot find any project settings concerning it.

According to frontend/project/new/new-file-page.tsx

...
function blocked() {
    if (project_map == null) {
      return "";
    }
    if (get_total_project_quotas(project_id)?.network) {
      return "";
    } else {
      return " (access blocked -- see project settings)";
    }
  }
...

              <NewFileButton
                icon={"cloud"}
                name={`Download from Internet URL ${blocked()}`}
                on_click={() => createFile()}
                loading={downloading_file}
              />

it somehow related with Project Quota Settings that moved to «Quotas and Upgrades»,
but here I also cannot find corresponding setting.
