Business Central AL return customer default dimensions as part of /customers endpoint

I am creating essentially an extension of the default get customer endpoint, but need to return dimensions as part of the /customers endpoint, so part() won't work for me. I presume I need to do something along the lines of this:

var
Dimensions: Text;
 
trigger OnAfterGetRecord()
var
    TDimensions: Record "Default Dimension";
begin
    TDimensions.Reset();
    TDimensions.Get();
    Dimensions := TDimensions."Dimension Code";
end;

But obviously need to pass in some "query" stuff to specify what data I want, but not really sure how. Any help is much appreciated.

Ideally I would like to have the full list of Dimensions

For anyone interested in the future, this was the solution that worked for me. Thanks to Natin Verma on the Microsoft forums

var
    Dimensions: Text;

trigger OnAfterGetRecord()
    var
        DefaultDimension: Record "Default Dimension";
        DimensionText: Text;
    begin
        // Clear the Dimensions variable for each customer record
        Dimensions := '';

        // Filter Default Dimension records for the current customer
        DefaultDimension.Reset();
        DefaultDimension.SetRange("Table ID", Database::Customer); // Table ID for Customer table
        DefaultDimension.SetRange("No.", Rec."No."); // Filter by the current customer's No.

        // Loop through all dimensions for the customer
        if DefaultDimension.FindSet() then begin
            repeat
                // Append each dimension code to the text (e.g., "DEPARTMENT,PROJECT")
                if DimensionText = '' then
                    DimensionText := DefaultDimension."Dimension Code"
                else
                    DimensionText := DimensionText + ',' + DefaultDimension."Dimension Code";
            until DefaultDimension.Next() = 0;
        end;

        // Assign the concatenated dimension codes to the Dimensions field
        Dimensions := DimensionText;
    end;
