how to upgrade add-on

hi, i purchases igui extension from the asset store and as of today a new version is available. Anyone know how i would upgrade my extension? Do i re-download the entire thing or there is an update option somewhere in the asset store?

I just updated my Qualcomm AR add-on yesterday. Visiting it in the Asset Store has the link, instead of 'Buy' or 'Download' said 'Update' Hopefully that will work for you.
