At the very bottom of the text input options, look for "Allow user to skip this node if"... since it sounds like you want this to be ALWAYS optional/skippable, you need to give this a condition to always return true.
If you don't mind low code, you can click script and in the function, simply have "return true;".
If you want no code, just Add Condition to something that will always return true. The first thing that comes to mind is "User is not empty" (note: we don't have unauthenticated users - if you do, you probably don't want this) - though you can also do something like "User is not [some system account]" (presuming you have at least one system account in the User table).
