Does the discharge of light, transparent fluid from a woman during a phone conversation with her fiancé invalidate the fast and necessitate ghusl?

The suitor is a stranger to his fiancée before the legal marriage contract. Therefore, it is not permissible for them to be in seclusion together, nor to engage in sexually provocative speech, especially during Ramadan. As for what was discharged from you, it appears to be madhy (pre-seminal fluid), which, according to the majority of scholars, does not invalidate the fast and does not necessitate a full ghusl (ritual bath); rather, it is sufficient to wash what it touched. If it were actual maniyy (seminal fluid), it would necessitate washing the entire body, but there would be no obligation to make up the fast since it was discharged merely through thought.
