Hi, I was working on a school project I needed to create a canvas that fills all the remaining width but upon creating the flex box container my chat div wont join/enter the flexbox.

From what I can see you have a lot of positioning going on that is somewhat unneeded when using flexbox. Ill give you a basic example. First I set all objects to box sizing border-box to help when using percentages. Position your container with position fixed and place it on the top right (you already have this done). Make it display flex and give it a flex direction of column so the objects stack on top of each other. Give it a height and width. I use vh(viewport height) and vw(viewport width). Next your message area will have a property called flex-grow that is set to 1. This allows it to take up all the remaining available space. Next set the height on your chat container I set mine to 25 viewport height. This means your message area will take up all but 25% of the viewport height. Then I just set the height and width of the chat textarea to 100% and since it now uses border-box box sizing it will just fill the container.
Flexbox and Grid are there to help you position objects while keeping them in the flow of the document so be careful when using position absolute when trying to move objects around. Here is a really good guide to flexbox: https://css-tricks.com/snippets/css/a-guide-to-flexbox/ and here is more information on positioning. Take a good look at how absolute moves objects out of the normal flow of the document https://developer.mozilla.org/en-US/docs/Web/CSS/position

Incase the first answer does not help Ill give you an example on how to position objects using flexbox. This keeps objects in the flow of the document and manipulates their position using display flex, flex direction and flex grow.
body {
margin: 0;
padding: 0;
}
.wrapper {
display: flex;
height: 100vh;
width: 100vw;
}
.remaining-area {
flex-grow: 1;
background-color: #f2f2f2;
}
.chat-area {
width: 30vw;
height: 100vh;
display: flex;
flex-direction: column;
}
.message {
flex-grow: 1;
background-color: #ccc;
}
.chat {
height: 25vh;
}<div class="wrapper">
<div class="remaining-area">
<p>this area is left empty</p>
</div>
<div class="chat-area">
<div class="message">
<p>message area</p>
</div>
<div class="chat">
<p>chat area</p>
