Ensure that you are logged in to Yumpu.
Open the webpage where the embed is located in the same browser.
Locate the embed and click on the "Embed" icon in the bottom right corner.
In the "Advanced" options, you can make the desired edits to your embed.
After making the changes, remember to save them.
Note that the embed code and URL will remain the same.
