title: How to put INTENT_CONFIDENCE asserter as a global variable in Botium
body: <p>My question is about how to set the INTENT_CONFIDENCE as a global asserter instead of put it all over the convos. </p>
  
  <p>I tried it two ways in botium.json configuration file, but both are not working: </p>
  
  <p>within the "ASSERTERS" capability, I tried:</p>
  
  <pre><code>  "INTENT_CONFIDENCE": 100 -- I have done the same but with "100"/ "100 %"
  </code></pre>
  
  <p>and </p>
  
  <pre><code>  "ref": "INTENT_CONFIDENCE", 
    "val": "100" 
  </code></pre>
  
  <p>the error looks like </p>
  
  <pre><code>AppData\Roaming\npm\node_modules\botium-cli\node_modules\yargs\yargs.js:1133
        else throw err
             ^
  
  Error: Failed to fetch package botium-asserter-undefined - { Error: Cannot find module 'botium-asserter-undefined'
  </code></pre>
