After a while for researching the solution for this issue, we found an exciting answer. The upload option and insert an image from My Drive option come back as a magic when we switched to a Private window for changing the signature. So the reason is this option isn’t displayed if a user is signed in to multiple accounts. So finally, the solution is sign into an Incognito window or clear the cache and cookies.
