ArcGIS AI Components (`<arcgis-ai-chat>` / `<arcgis-ai-assistant>`) - Unable to query related tables

HexamapSolutionsPvtLtd

Hi everyone,

I'm evaluating the ArcGIS AI Components (`<arcgis-ai-chat>` / `<arcgis-ai-assistant>`) with a web map hosted in ArcGIS Online and would like to understand whether the behavior I'm seeing is expected or if I'm missing any configuration.

Environment

* ArcGIS Online
* Parcel feature layer
* Related tables:

* `owner_table`
* `documents`
* `tax_assessment`
* `agreement_status`
* Relationship classes created in the file geodatabase
* Data published to ArcGIS Online
* Relationships are visible in the ArcGIS REST Services Directory

What I have verified

* Relationship classes exist in the geodatabase.
* Relationships are published correctly.
* Related tables are available in the hosted feature layer.
* The AI assistant can successfully query parcel layer attributes.

Tests performed

Layer detection

* Prompt: `What are the layers available in the map?`
* Result: Only detects the vector layer.

Layer visibility

* Prompt: `Turn off the parcels layer.`
* Result: Not working.

Zoom to layer

* Prompt: `Zoom to parcel layer.`
* Result: Working.

Feature count

* Prompt: `Feature count of the parcel layer.`
* Result: Working.

Query feature

* Prompt: `Show parcels where tenureType = 'Freehold'.`
* Result: Working.

Highlight feature

* Prompt: `Highlight the parcel feature where parcel id is 1.`
* Result: Working.

Change symbology

* Prompt: `Can you change the color of the parcel layer?`
* Result: Not working.

Query related table

* Prompt: `Get the doctype of the feature where parcel id is 2.`
* Result: Not working.

Parcel layer attributes

* Prompt: `List the attributes of the parcels layer.`
* Result: Working.

Parcel attribute values

* Prompt: `List all owner names from the parcel layer.`
* Result: Working.

Buffer creation

* Prompt: `Create a buffer from the parcel where id is 3.`
* Result: Not working.

Last clicked location

* Prompt: `Can you give me the latitude and longitude of the last clicked point on the map?`
* Result: Not working.

Main issue

The AI assistant correctly answers questions based on the parcel layer attributes, but it cannot retrieve values from related tables such as `documents`, `owner_table`, `tax_assessment`, and `agreement_status`.

For example:

* `Get the doctype of the feature where parcel id is 2`
* `Show the agreement status for parcel id 1`
* `Show the tax assessment for parcel id 3`

These queries do not return the expected results, even though:

* The relationship classes exist.
* The relationships are published successfully.
* The relationships are visible in the ArcGIS REST Services Directory.

Is querying related tables through relationship classes currently supported by `<arcgis-ai-chat>` / `<arcgis-ai-assistant>`?

If not, is there a recommended approach or sample implementation for enabling this functionality? Additionally, are operations such as changing layer visibility, changing symbology, creating buffers, and retrieving the last clicked map coordinates currently supported, or do they require custom tool integration?

Any clarification or guidance would be appreciated.
