How to check for free cells in a line in the costmap?

Hello, What I want to do is something similar to a raycast. From a specific position draw a line and get the list of all the free cells in that line. The line has a maximum length, but it has to stop if it reach an obstacle. Is there an existing API for that? Or I need to implement it myself?

Thanks!

In the end I solved it by implementing a new layer on the costmap and using this:
