[support] openlayers_proximity module contextual filter

Hello, I am having trouble with the openlayers_proximity module 7.x-2.x. I just cannot get it to show up in the contextual filters of views. Does anyone else use this module? If so, i think the problem might lie with the versions of geofield or open layers. Which version are needed to get proximity as a contextual filter? Thanks a lot in advance! Christian
