Escape key disappeared from Touch Bar

hi 👋

I got my self a new MacBook Pro last month. At the beginning whenever I pressed the "fn" key I had on the TouchBar "esc" key and all the F's 1-12th. but, now, when ever I press the "fn" key I have only the F's keys without the esc key.

I don't know what I did that made the "esc" key disappeared from the Touch Bar but I hope that someone knows how to make it appear again.

thank you 😊 🙏 ☺️
