How to use IFrame extension

Please help i dont get how to use the embed extension or the “Dom ID” idk what dom id is

DOM id is just the name for your iframe to be able to delete it with the delete action, you can choose any one.

oh ok thanks i was stuck lol

for some reason it just shows as a blank project though

Websites can prevent others from using them in iframe.
You can test it with they allow it.

oh thank you it works now
