In workflow code use the replay safe logger you can get via Workflow.getLogger. Some examples:

Workflow.getLogger(this.getClass().getName());
Workflow.getLogger(this.getClass());
Workflow.getLogger(MyWorkflowImpl.class);

In activity code you can use a logger of your choice.

Are these logs visible from UI (Temporal console)? I was not able to find the customized logs there. Any additional steps to emit it?
