How should a girl pray to her Lord to make her manager forget the gestures and allusions she made during her conversation with him?

Mend your relationship with Allah Almighty, and He will mend your relationship with His creation. Repent to Allah Almighty and do not return to the likes of what you have done. When your repentance becomes apparent and you avoid speaking with men except out of necessity, and your speech with them is neither submissive nor overly soft, the perception of you will change. We also alert you, dear sister, that it is not permissible for a woman to uncover her face in front of a non-mahram man whom she knows is looking at her. Seclusion between a woman and a non-mahram man is forbidden and impermissible. Know that working in places where non-mahram men are present is a slippery slope and can lead to undesirable consequences. So, hasten to leave such work if you are not compelled to it.
