If you don't want to show Product Fruits branding (we won't be mad) from the Life Ring Button and Feedback widgets, you can use the following snippet:
.productfruits--branding {
visibility: hidden;
}
To remove the 'powered by Product Fruits' from the bottom of your knowledge base, the snippet below can be placed in the 'Body HTML or script tags' field of the Custom HTML & scripts tab.
<style>
#__next > div > div.footer.p-5.w-full.mt-10.text-slate-300.z-10.kb-footer > div {
visibility: hidden;
}
</style>
