Widgets Are Not Accessible
Many companies sell accessible "widgets" that you can place on your website. They claim that these widgets somehow many your website WCAG 2.1 or ADA compliant. This is not true.
Generally what those widgets do is attempt to emulate assistive technologies (AT) that those with disabilities might use. The problem is, your disabled visitors already have their own AT solutions and that is not what they need. They need your code and your content to be constructed in a way that when their readers encounter it, they can make sense of what is being shared.
When a screen reader reads "mandatory field 1" you can be pretty sure that is not going to help that customer know what they are supposed to enter.
