You probably want a display filter on TCP (or UDP) port. Most applications will use a specific port along with protocol (TCP or UDP) to identify which specific application is sending and receiving the data on the network.
Here is an older question with some details: https://osqa-ask.wireshark.org/questions/41300/filter-with-destination-port .
Here is some info as well.
Do you know which port and protocol your specific application uses?
It is possible to do a capture filter where only the specific traffic you want is captured and saved for analysis. I don't recommend this in the beginning until you know exactly what you are looking for so I would capture everything then use display filters to hide the trivial many packets from the critical few you are looking for.
