OTP for group member

if organization has multiple group members with same vat number
each group member need different OTP ?
or all will be same with one OTP and different CSR and CSID?

Kindly note each OTP can be used to request a single CSID. OTPs must be used to onboard the EGS units of the same Taxpayer from whom the OTP request has been made from the Fatoorah portal.
