Why can't I type in the SSH Key field when creating a cloud cluster?

I am trying to create a cloud cluster using AWS in MATLAB R2021a. To do so, I navigate to the Cluster Profile Manager and select Create Cloud Cluster. When I get to the last step, I have to fill in my SSH key which is a required field. However, I cannot type any information into this field. Furthermore, it seems that there's a dropdown key that is blocked by an exclamation mark icon which seems to block me from clicking on this.

How can I get my cloud cluster set up properly?

Use the steps from the documentation below for creating the cluster using Cloud Center instead:
