If I'm not mistaken, it seems there is also a Telegram bot that can provide transaction notifications for addresses in our wallet. but I forgot which bot.
There are many options to watch your wallets like creating a watch-only wallet to check its balance, transaction history. You can bookmark that address on a browser to check. Other options like receiving notifications through email, SMS, telegram but honestly I would like to do it all by myself on my devices. Relying on third party tools can leak my privacy.
If don't care about privacy, considering this one.
