Embedding Google Sheet and having issues. Please help!

Hi.  I am trying to embed a Google Sheet on my webpage: https://expandingeducation.squarespace.com/resources

Password EETest2024

Currently it is not displaying correctly and I assume that it has something to do with the embed code:

<iframe src="https://docs.google.com/spreadsheets/d/e/2PACX-1vTtf5FIF3GWuHElaQs8VZbBoTIryqy1qQkl1oMHUVeIcDnQYgRRtoBmu9_SREwjNBjFEvfwj_CxiUwX/pubhtml?widget=true&amp;headers=false"></iframe>

Can someone please help?

You can use this code to Website Tools (under Not Linked) > Custom CSS.

div#block-yui_3_17_2_1_1719026074174_4543 iframe {
    width: 100% !important;
    height: 700px !important;
}
