how to DETECT_MOTOR_FLUX_LINKAGE

[RKajay2001]

i use this code
class DetectMotorFluxLinkage(metaclass=VESCMessage):
""" Detects the motor flux linkage value.
"""
id = VedderCmd.COMM_DETECT_MOTOR_FLUX_LINKAGE

fields = [
    ('flux_linkage', 'i', 1000)# Adjust the scale as needed for the result
]

but it won't give the correct answer which was given in the vesctool but the same method is working for DETECT_MOTOR_R_L
