How can I change the fill color of selected SVG icon in PowerPoint web add-in using Office.js

Question

I'm working on a PowerPoint web add-in using Office.js, and I'm trying to change the fill color of selected shapes in a slide. I wrote the following function to change the color, but it's not working as expected. The SVG icon is coming as an image and hence, I'm not able to change the color of the SVG icon.

async function setFillColor(color) {     await PowerPoint.run(async (context) => {         const selectedShapes = context.presentation.getSelectedShapes();         selectedShapes.load("items");         await context.sync();         await selectedShapes.items.forEach(async (shape) => {             if (color != "") shape.fill.setSolidColor(color);             else shape.fill.clear();         });     }); }
