Scrapy-Splash: Cannot click buttons with lua script

Question

I am scraping data from grammy.com and I would like to expand tabs containing the information related to Grammy Awards (Image enclosed below).

I wrote a lua script to go through and click all the buttons but there does not seem to be any change to the html I received. Here is the sample page and the lua script is as follows:

function main(splash)
    assert(splash:go(splash.args.url))
    splash:set_viewport_full()
    assert(splash:wait(1))
    local btn = splash:select_all('button[class^=cursor-pointer]')
    for key , value in pairs(btn) do
        value:click()
        splash:wait(2)
    end
    return {
        html = splash:html(),
        png = splash:png(),
    }
end

Any help is much appreciated. Thank you in advance.
