In the 15th General Election, Lim contested for the first-time and won the Tanjong parliamentary seat under the Pakatan Harapan ticket.

On 27 March 2023, Deputy Speaker of the Dewan Rakyat Ramli Mohd Nor reprimanded Lim over the failure of not preparing an answer for the oral question-and-answer session.

However, Lim told the Dewan Rakyat that she had not prepared an answer, and asked to submit a written reply.
