No. The sanitization process is there for very good reasons and cannot be overseeded. By trying or doing so, you’ll run into issues you’ll receive no support for and that are not bugs and thus are no issue candidates.
Yes I know. Sanitization should be done for some kind of tags and scripts. But removing CSS styles like colour and background is not necessary at all, is not a risk for security. However, could be fine if the sanitization is done in customer - agent side, assuming is malicious actor, but, what’s the point of doing this via API with an admin account?
