How can I scrape dynamic website with R?

Question

I want to scrape this website. But for button clicks, can't add HTML nodes.  I'm using RSelenium.

Land <- remote_driver$findElement(using = "class", value = "_10ALxoWWyBGfz0jUBNjyCC _3ohT4jOEoF5q1xJlci1ELO")

Land$clickElement()

As a result, get error like this:

Error: Summary: InvalidSelector

  Detail: Argument was an invalid selector (e.g. XPath/CSS).

Further Details: run errorDetails method

I'm getting elements from HTML inspect and id values for the text boxes works well.

Does anyone have any solution to this problem?
