Do I need a matching network for RFM96W + chip antenna?

Do I need a matching network for RFM96W + chip antenna?

Hi,

I’m using an RFM96W LoRa module and want to connect this chip antenna:

Can I connect it directly to the ANT pin, or do I need a π matching network on the PCB?
I need long-range communication but I have limited space, so I’m wondering if I can skip the matching network or if it’s essential for proper performance.
