Hello can you guys help me with this problem
I got some problems that I cant get the polygon graphic uid
I want to set attributes for the textsymbol with it get the id from the polygon graphic uid
Here the coding:

if (graphic['geometry'].type == 'polygon') {

const rings = graphic['geometry'].rings;

const polygon = new Polygon({

hasZ: true,

hasM: true,

rings: rings,

spatialReference: graphic['geometry'].spatialReference

});

const fillSymbol = {

type: "simple-fill", // autocasts as new SimpleFillSymbol()

color: [0, 0, 0, 0.1],

style: 'solid',

outline: {

color: 'red',

width: 2

}

};

// Add the geometry and symbol to a new graphic

const polygonGraphic = new Graphic({

geometry: polygon,

symbol: fillSymbol,

attributes: lineAtt,

popupTemplate: popup

});

// Add text symbol

const textSymbol = new TextSymbol({

text: graphic['attributes'].name, // or any other attribute you want to display as text

color: 'red',

font: {

family: 'Arial Unicode MS',

size: 15

});

const point = new Point({

longitude: graphic['attributes'].centroid.x,

latitude: graphic['attributes'].centroid.y

})

const textGraphic = new Graphic({

geometry: point,

symbol: textSymbol,

attributes: {

// id: polygonGraphic.uid // Use the UID of polygonGraphic as the value for the 'id' attribute
