I will prefer not to use any telegram not for this reason, there is a wallet that I am using that has the characteristics but I am still using Electrum also on my mobile phone because it is a very good wallet. It is not up to what I need to sacrifice my privacy for.
As you seem to care about your privacy, it may be worth mentioning that unless you run your own server, even in electrum, you connect to servers provided by third parties and they can link your bitcoin addresses to your IP address.
Is there a way to create a watch-only wallet in that other wallet that has the feature that you need?
By the other wallet, OP meant BlueWallet, as mentioned in
this post, and as you know, it supports creating a watch-only wallet.
