Embedding Playlist in Widget Area in Wordpress - Only Showing Short Box

[HideTapes]

WordPress Version:

5.4.1

Plan:

Premium

Country:

USA

Device:

(Macbook Pro Early 2011)

Operating System:

(macOS Sierra 10.12.6)

When embedding a playlist in the widget area of my Wordpress site, its only showing a short box instead of the longer rectangle (I've attached an image of what I'm seeing).

I did a quick search and I found another post describing the same thing but no responses unfortunately (https://community.spotify.com/t5/Other-Partners-Web-Player-etc/Embedding-Spotify-to-Wordpress-Only-S...)

The url of the page is: https://hidetapes.com/coronacion/

The url of the playlist embedded is: https://open.spotify.com/playlist/4iim1fN6BBD2HXOkk8mUnd?si=AUuVj0ROSmi1DLPJlSf2xg

I appreciate any help on this topic, thanks.

I figured it out; you have to apply custom css for the iframe embed shortcode. I used this article as a reference: https://keithjlang.com/how-to-put-spotify-playlist-wordpress/
