import { ENV } from "https://deno.land/x/permissionGuard@2.4.0/mod.ts";
The "powerful feature" "env" which needs permission.
See:
- https://w3c.github.io/permissions/#status-of-a-permission
- https://github.com/denoland/deno/blob/master/cli/js/lib.deno.unstable.d.ts
Note that the definition of PermissionName in the above spec is swapped
out for a set of Deno permissions which are not web-compatible.
