Read receipts let the other person know you’ve seen their message. You can send
them programmatically and receive them via webhooks when someone reads your message.
const receipts = await client.listReadReceipts({ from: "+15551234567", to: "+15559876543",});for (const receipt of receipts.data) { console.log(`${receipt.handle} last read at ${new Date(receipt.lastReadAt)}`);}
