Hello Alexander,
I apologize for the long delay in responding.
YouTube videos can be embedded, but you must use the "embed link". To get the embed link, click "Share" on YouTube and then "Embed". Copy the embed code and then paste it somewhere that you can edit it. The embed link/URL is in that code -- it's the part in between the quotation marks and starts with "https://"
You would use the same process (looking for the embed link/URL) for a Google Form and some other tools that use embed codes.
Often the instructions for these tools are on this
help document. If anything is missing, please let me know!
