RAI flag on BG770A

Does BG770A support AS-RAI or is there just CP-RAI (NAS-RAI) support?
Is there any difference in using AT+QCFG="raiflag" or AT+QISENDEX for specifying it?

AT+QCFG=“raiflag” It will attach the RAI flag to every uplink packet
AT+QISENDEX It implements RAI features only through UDP methods

Thank you. What about the AS-RAI support? Is there support for RAI in LTE-M networks? Right know I don’t know if I’m waiting for firmware upgrade or network upgrade for this to work properly.

RAI may not be supported on LTE-M
