Why does the Telegram need to use its own User Agent? The in-app browser is not written by Telegram anyways, it's a Safari.
Facebook & Instagram's in-app browsers are made by the company themselves, therefore they use custom user agent strings.
On reason it is actually very useful to be able to detect whether a site was opened in the Telegram web browser:
I'm honestly a bit surprised that this isn't something that has been considered, it seems like a lot of people / their users must be running into this?
I have a similar issue: the in-app browser is not sharing the same localStorage as the full Safari, so it breaks a critical user flow. If telegram would have a specific user agent, we can advise users to use Safari for full experience or just 'Add to Homescreen'.

Description
We're developing PWA and when user opens link from Telegram it opens in in-app browser (which is similar to regular Safari) and there is no "Add to Home Screen" button in Share menu. We want to ask user to open that link in Safari, but we cannot detect if he is in Telegram in-app browser.
Expected Behavior
User-agent represents that this is Telegram (like in Facebook/Instagram apps):
