How to reduce the space between words but not kerning in my header?

Hi all,

Anyone know how I can reduce the space between"Hi" "I" "AM" and "KACY"?

I attached my code and screenshot here:

// CUSTOM FONT
@font-face {
font-family: 'RobotomonoRegular';
src: url(https://static1.squarespace.com/static/6661474b09bd7e53f3048c41/t/6675b66313e7f029aa9cf88c/1718990441965/RobotoMono-Bold.ttf);
}

  
  h1 {
font-family: 'RobotomonoRegular';
font-size: 36pt;
letter-spacing: -1px;
line-height: 100%;
color: #565656;
}

Many thanks!

@Kacy-Jung Hi! Try adding this code under Custom CSS

#block-yui_3_17_2_1_1717776332332_9521 span.sqsrte-text-color--custom {
    word-spacing: -0.3em;
}
