How to update a register in a collection MAP list?

Looking for a solution, hope you can help me!

First of all, I have doubts if it's a database issue or an action issue.

I'm passing data through Page Parameters from a list view on page 1 to a page where I want to update information in a specific register in Firebase.

Turns out that information that needs to be updated is on a collection map that contains a vehicle list.

Flutter Flow has the options below available.

Trying first selecting docRef which is the reference of the vehicle collection that identifies the vehicle in this map.

The only available option isn't selectable.

Now trying allData that brings the entire collection that possesses my_vehicles map. It allows you to select Get Document Property on available options.

Then I can select the map my_vehicles.

Then Filter List Items by Doc Reference and again get blocked to select the only option available.
