How to extend the core component teaser to accept webp format images? Hello, what happens is that I want to allow the core teaser component to allow the user to upload images in webp format. The core component is as default, the only thing I modified was the _cq_dialog and the .content.xml file. <column jcr:primaryType="nt:unstructured" sling:resourceType="granite/ui/components/coral/foundation/container"> <items jcr:primaryType="nt:unstructured"> <file jcr:primaryType="nt:unstructured" sling:resourceType="cq/gui/components/authoring/dialog/fileupload" class="cq-droptarget" fileNameParameter="./fileName" fileReferenceParameter="./fileReference" mimeTypes="[image/gif,image/jpeg,image/png,image/tiff,image/svg+xml,image/webp]" <------ Just add image/webp name
