cannot paste my metadata keychain password I am following the steps in How do I stop &#39;mdwrite wants to use the &quot;metadata&quot; keychain&#39; prompts?

But having a problem, I am unable to type the crazy password into the system dialog that comes up, and copy-paste does not work. Because it is stealing the input focus, I cannot do much else. I had to manually type the password. Is this a Mac Bug? Or am I just doing it all incorrectly. 

(Mac Mini on Catalina, while editing xcode project options/targets after locking keychain) Otherwise pretty much exactly as in the link.
Clear the input field of the &quot;mdwrite wants to ...&quot; pop-up
Get the &quot;metadata&quot; login password
Put your cursor in the input field of the pop-up
Go to the menu and under &quot;Edit&quot;, go down and click &quot;Paste&quot;.
Worked for me, because right-clicking while the mouse was in the field had the usual editing pop-up come up behind the &quot;mdwrite ...&quot; pop-up.
I'd never seen that before, but some pop-ups must have a higher priority than others ...
