suggestion about pin message

After uploading a link or image, if you click 'Pin Message' to fix it, the size of the embed related to the link is arbitrarily cut, and the preview appears in a strange shape instead of the whole. It is suggested that this content be reduced/enlarged according to the size of the embedding/image.
