I'm not very familiar with this source [0], but it states "ESA was providing support to the Chandrayaan-3 mission from three of its ground stations located in Kourou (French Guiana), Goonhilly (United Kingdom), and New Norcia (Western Australia)." Although BIK doesn't obviously map to any of those.
“ISRO and LAPAN have had a long history of collaboration, with ISRO owning a ground station on the Indonesian island of Biak, which has supported many of India’s launches.”
