YouTube under header before recent posts

First of all thanks for sharing such a beautiful theme for video posting. I tried many themes but could not get the videos in the blog archive. Most of them displaying only thumbnail and once you are in single post view they show the video. The way your theme worked with some plugins is amazing. Again, kudos to you.

Now, I want to show a YouTube video under the header and before the recent posts area.
This is the homepage of the blog I would like to embed the YouTube video:
https://homevideofitness.com/

I have made a test page and entered the following code in the HTML block and it is showing on that particular page but do not know how to put it on the front page.

<p><iframe width=”560″ height=”315″
src=”https://www.youtube.com/embed/njeZ29umqVE?playlist=njeZ29umqVE
&mute=1
&autoplay=1
&loop=1″>
</iframe>
</p>

Any help will be greatly appreciated.
