JNLP slave workspace

Hello guys,
I am trying to implement dynamic slave in jenkins using kubernetes plugin. The architecture is set up and the job is successfully built using jnlp agents. But I am not able to access the Workspace as it gets removed as soon as the built is done. I need the built artifacts to store in the Nexus repo but I am not able to access the slave workspace.

Can anyone help me in this. I would really appreciate your support.

Thank you
