How to add a button with time delay?

Dear,

I want to add 1 button to 1 specefic page. The button must be shown after a certain time period, so it has to go from invisable to visiable

How do i set this up?

Thank you in advance!

@AM349 I would require more details like,  page url and which button. Also the time period (in seconds) to give you a precise code

@TheSquareSpacer thank you for your fast reply!

Here are the details you asked for:

- page url: bevrijdjezelf.com/webinar (it is a webinar page where we are selling a course)

- It's is about the large orange button underneath the video with the text ''bevrijd jezelf''

- the button should appear after 620 seconds.

Thank you in advance!
