Vimeo embed, WCAG compliant

What to think of when you embed Vimeo videos into your website.

Add the title attribute into the iframe element. Describe in a few words the content of the video. (SC 4.1.2)
Add subtitles, if there is spoken words or important sound effects in the video (SC 1.2.2)
Add audio description, if necessary (SC 1.2.3, SC 1.2.5)
Use enough contrast for text in the video (SC 1.4.3)
Disable keyboard short cuts, set keyboard to false. Tabbing still works. This setting exists since version 2.16.0 (Aug. 2021). (SC 2.1.4)
Do not use autoplay. Default in Vimeo's player.
Show controls. Default in Vimeo's player. Necessary in case of autoplay (SC 1.4.2)
Keep full screen option available (yet, have to find that one out)
Present a link to Vimeo so the user can easily watch the video on the Vimeo platform or Vimeo's app.
