Clickable thumbnail for a widget

I’m using the Leaflet map plugin. I have a map that is generated by the widget:

<$leafmap tile='natgeo' places='{"filter":"[tag[Places]]"}' zoom='4' marker='pin' color='blue'/>

How can I call this from a clickable thumbnail image on another tiddler?

This isn’t really about the Leaflet map plugin but generally how you can create a link that works from an image, something like this but with the correct syntax:

<$link to="{{<$leafmap tile='natgeo' places='{"filter":"[tag[Places]]"}' zoom='4' marker='pin' color='blue'/>}}" tooltip="Location map">{{thumb/image}}</$link>
