Inserting dynamic text from related table for Data Driven Pages of ArcMap?

Question

I'm trying to insert a dynamic text from a related table in a ArcGIS layout using the Data Driven Pages feature to generate automatic reports based on attribute table from a feature class.

I have a geodatabase with a feature class and a related table downloaded from Survey123 for ArcGIS.

Here's the schema of the geodatabase. The source layer used in DDP is "_3410__Campanha_de_Comunicacao_para_Fase_de_Estudos", and the related table is the "Stakeholder" file.

I do not think that this can be done within ArcMap using Data Driven Pages.

It may be possible to do using Map Series and Table Frames within ArcGIS Pro, but I have not tested that.

I am confident that it can be done using ArcPy with "table-like feature classes" in ArcGIS Pro and ArcMap.

For ArcGIS Pro the necessary coding patterns are taught in an eLearning video course on Udemy called Challenging times with Python and ArcPy for ArcGIS Pro. It is not free, and it uses ArcGIS Pro rather than ArcMap, but the coding patterns taught use functions with equivalents in ArcPy for ArcMap.
