At her blind audition, she sang "Halo" by Beyoncé, and had all three coaches turn their chairs for her, eventually joining the team of Polish singer-songwriter Edyta Górniak, who represented Poland at the Eurovision Song Contest 1994.

[7][8] In October 2018, Węgiel collaborated with Górniak on the single "Zatrzymać chwilę", recorded for the soundtrack of the Polish version of the film Hotel Transylvania 3: Summer Vacation.

[9] On 21 September, Węgiel was announced by Polish broadcaster Telewizja Polska (TVP) as Poland's entrant in the Junior Eurovision Song Contest 2018, to be held in Minsk, Belarus.

[10] Her song for the competition, titled "Anyone I Want to Be", was written by an international team consisting of Polish singer Lanberry, Danish producer Cutfather, American songwriter Maegan Cottone and Danish-Norwegian musician Daniel Heløy Davidsen.

[14] The competition was held on 25 November, where Węgiel was eventually crowned the winner, placing first with the viewing public and seventh with the professional juries.

[15][16][17] On 12 April 2019, Węgiel released the single titled "Lay Low", which drew criticism for its racy lyrics branded by some as inappropriate for her age.
