Hi @ninabaksh, thanks for reaching out and sorry for the delayed reply (due to the weekend).
Unfortunately, there is no trial for our templates but you can check the preview link of the template to make sure the template looks and works as expected.
Within the current template functionality, you are able to link an existing video URL to the post.
I’m afraid that currently, the template doesn’t provide any other possibilities to link already existing content sources. Sorry for the inconvenience.
Kindly note that as all our templates are fully customizable, such feature could be added through application customization (corresponding Bubble skills are required).
Please let me know if I can help with any other template-related questions .
