After joining BNK48, she was nicknamed by her fans as "ลูกพี่" (IPA luːkpʰîː, meaning 'gang leader' in Thai), probably due to her (then) big biceps, no-nonsense attitude and rather direct style of communication.[3]

Jennis also took part in BNK48's First General Election. The final result was announced on 26 January 2019, in which she ranked as no. 2, with the total voting points of 58,362.[7] The outcome was regarded as a surprise for many people,[8][9] for in the first preliminary result, her rank was 6 and it remained so in the second round. In her election speech, Jennis thanked her supporters, saying "her miracle was actually her supporters".[10]

As a result of the election, she was one of the three front-row members in BNK48's 6th single "Beginner". A day later, she, along with other BNK48 members, joined the concert AKB48 Group Asia Festival 2019 in Bangkok. She was part of a special unit, the so-called World Senbatsu (WRD48) unit, and performed in the song "End Roll", along with Mao WeiJia (AKB48 Team SH), Shani Indira Natio (JKT48) and Abelaine Trinidad (MNL48).[11]

The band is the collaboration between BNK48 and Universal Music and will focus on T-Pop genre.
