How about changing the emoji depending on the types of requested permission?

✍️ Deno requests write access to "example.txt". Grant? [yN]
🔍 Deno requests read access to "example.txt". Grant? [yN]
🌐 Deno requests network access to "https://example.com". Grant? [yN]
🏃‍ Deno requests access to run a subprocess. Grant? [yN]
