Cannot scrape element

Hi
I'm not sure if the method I'm using is correct or if it's possible but on this site Bus map , I want to collect the bus data which is represented with the red nodes moving. I'm using the element type to select all the buses but I'm not able to select the text when the node is clicked and tried to use the element click but couldn't figure it out

{"_id":"livelondonbus","startUrl":["https://traintimes.org.uk/map/london-buses/#73"],"selectors":[{"id":"busSelector","type":"SelectorElement","selector":"g:nth-of-type(n+64) path.leaflet-clickable","parentSelectors":["_root"],"multiple":true,"delay":0}]}
