Here is a very simple running code snippet that uses XPATH to find the button Text "Se flere".
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("https://coop.no/sortiment/obs-bygg/hageuterom/hytter-boder-og-
drivhus")
element = driver.find_element_by_xpath('//button[text()="Se flere"]')
element.click()
