Aligning the UX and UI methods with the Design Thinking Process, can you categorise them?

The Design Thinking Process consists of Empathy, Define, Design, Prototype, and Test. While the last two phases are straight-forward, i.e Test might include usability testing, A/B Testing, etc. and Prototype might include interactions, micro-animations, states, etc. I need more clarity on the initial phases.

For the Design Phase, we might have wireframing, IA, etc. But will the user personas and flows be part of design or define? Especially what will come under Empathy is something that I am stuck at.

In short, mapping the UX Research and UX Design (and UX Testing) with the Design Thinking stages.
