Show the geofield field of an entity reference

Hello,

I have a content type "reunion" with a reference to an other content type "lieu". In "lieu" i have a "field_geofield" which i want to print into my "reunion" node.
Actually, I tried this :
{{ node.field_lieu.0.entity.field_geofield.0.value }}
Which works, but not as I would like. Indeed it shows me this: POINT(1.080064 49.428707).
I would like to have a map display (leaflet), as in my "lieu" content.
