There is no button "Open in web" in Telegram

This needs more description to be able to help troubleshoot.
From where is that screenshot? Telegram web itself or another site?
Is Telegram web already logged into in another tab?
Are these tabs in the same container?

[lament pendant]

the site was made from a link when going to the telegram channel, I'm logged in to the telegram web.

does this same issue occur in any other browsers?
