To take a polygraph test or to not? TW

My narcissistic MIL and SIL have slandered my reputation within my husband's entire side of the family by saying they believe I molested my niece. These accusations are 1000% false and malicious to try and get me shunned and ostracized permanently. I've been thinking about ways I can prove that I would never and the accusations are ridiculous. The only way I think i would get any sort of vindication is by taking a legit polygraph test (yes I realize they're not always accurate) but it's the only thing I can think to do to clear my name. What do you guys think?
