'Google Sheets Dropdown "Input must fall within specified range". How to solve this?

I have a very simple Dropdown on Google Sheets that is working perfectly. Basically when I select an item from the dropdown, it will output that same item on another cell.

Works with dropdown items (see image)
Works with dropdown items (see image)

However, I also want to write a custom text (that is not available in the dropdown) to be outputed.

Here's what I mean exactly:

Not working when entering a custom text (see image)
Not working when entering a custom text (see image)

But I'm getting an error.

Is there a code that if you enter a text that is not in the specified range, it would display the text without an error?
