Is there a way to watch a prefix. I would like to be able to watch for any record added to a specific key prefix. ``` export async function logData(jsonObject: Object) { const timestamp = Date.now(); const id = nanoid(); try { console.log("set", timestamp, id); await kv.set(["dev-logs", timestamp, id], jsonObject); console.log("done set"); } catch (error) { console.error(error); } } ``` I want to be able to ``` const newLogs = kv.watch([["dev-logs]]) ``` And now I have an iterator that I can watch any new logs added.
