Facebook URL

Hi, I have a problem with adding FB to my WP site.
Although, In my footer my FB icon/favicon works as a hyperlink to open my FB site. I also want to add a FB widget but I cant make it work!

URL, https://www.facebook.com/weeadventours
Error: Not a valid Facebook Page URL

Then I read previous posts and tried URL, https://www.facebook.com/weeadventours-822277881153250/ also error

Then I clicked, use FB as and publish page (blank community page)?
WHY are they making simple complicated?

HELP
