Why Adobe PDF Embed API not showing AnnotationTools in Mobile browser?

[Kishan30889515xaqu]

We are working on a project where AnnotationTools works fine in Desktop browsers but doesnt even show AnnotationTools in mobile bowser. our code snippet for the viewerOptions:
const viewerOptions = {
embedMode: "FULL_WINDOW",
defaultViewMode: "FIT_PAGE",
showDownloadPDF: false,
showPrintPDF: false,
showLeftHandPanel: false,
showAnnotationTools: true
};

Can you guys tell me can we imlement that feture for mobile browser & if yes then can you provide us some solution for this ?
Thanks in advance.
