BG95-M3 MQTT Subcribe questions +QMTRECV: Buffer

I’ve got a few questions regard the subscribe functionality.

I am receiving notification of subscribed topics via the URC

+QMTRECV: 0,0, “Test/Test-subscribe”, “Hello World”

What I am wondering is if there is a way to control whether the incoming subscription notifications from the broker go in to the buffer so they will be reported via the URC

+QMTRECV: <client_idx>, <recv_id>

What controls whether they are received and stored by the buffer versus just being pushed as packet data?

Thanks in advance for any assistance.

Hoping to get a response from Quectel Support or someone else who has experience with this. Thanks.

When the module receives data from the MQTT server, it outputs the receive message via URC
