Grouping Coordinates in KNIME

I am currently facing a challenge and am reaching out with the hope that someone can provide assistance.

I have a list of coordinates (latitude and longitude), and I would like to group together all connected coordinates within a radius of 500 meters. My attempts so far have not yielded a suitable solution. My current approach involves assigning a unique identifier to these connected coordinates, but I am also open to alternative suggestions.

I have attached an example file to illustrate the issue. Could you please help me find a solution within KNIME to group these coordinates?

Thank you very much in advance for your support! Your assistance is highly appreciated.
