Alternative to copy or download generated QR (vue-qrcode) code using VueJs

I'm using the plugin "vue-qrcode" to generate a QR code for users to create a QR code for their public profile link so they can share it on their business card. The idea now is to give the user the possibility to download the QR code through a button and copy the QR code to the clipboard through another button to make it easier to send via email (especially for smartphone users).

Currently I'm using "vue-clipboard2" to copy links etc but can't seem to copy images.
