so I have a form and I want to add a regex validation so that no HTML tag is entered there. (i.e in some cases some people add <"b"> or some other HTML tags when entering a data) I want to avoid that by putting a validation in that form field.
This is one of the validation regex we use for email address, want something similar to reject HTML tags in being entered

This is the dashboard where I enter the validation for reference
