Get physical coordinates as a list (Tutorial 7)

Hi,
I have a question regarding obtaining the physical coordinates on which my weak form is evaluated. I came across Tutorial 7 at [https://gridap.github.io/Tutorials/dev/pages/t007_darcy/](https://chat.openai.com/url), which seems to address this issue.

It appears that using "px = get_physical_coordinate(trian)" provides the desired information. However, I am interested in saving these points in a list or vector for further use. Could you please guide me on how to achieve this?

Start with Tutorial 7 at the linked page and inspect how get_physical_coordinate(trian) is used. Determine how the returned physical coordinates can be saved as a list or vector, then document or demonstrate that usage and verify that the resulting collection contains the coordinates needed for further use.
