Hey, I saw the changes you have made.

The color scheme of the dialog doesn't seem to align with the overall theme. Additionally, the text theme appears to be somewhat inaccurate. In the provided screenshot, it's evident that the text color lacks visibility, and the dialog box color seems to overpower the UI color. I suggest exploring alternative shades to enhance the overall visual experience.

For reference, I came across an example in the Material 3 guidelines, which showcases a more cohesive and visually appealing design. Please consider implementing a similar approach, as demonstrated in the attached image.
