Snapping / aligning text to the top center of a specific face normal using geometry nodes

Question

How can I snap and align a string of text to the top center of a specific face using geometry nodes. I'm using Blender 3.0.1

Node setup below

Red Arrow is where I want the text to be

Note: I know I can just move the text manually but the goal is to learn / do this using GN.

Here's a way:

It goes:

• The input mesh has vertex normals; points don't. So capture the Normal field on points. It's a field, so will be interpolated when called on, to yield face normals.
• Center up the text to its Pivot Point using the String settings
• Select the point for instancing, by Index
• Align the instance's Z to the face normal, in the Instance to Points node.
