There is no "GET" in database button options?

While searching for a solution I found in Wix_data API:

But again this is unclear to me. I assume I could somehow replace the “00001” string with the value of dash_number as typed into the form? Also, in the example given, the results seem to be all COMMENTS?

import wixData from ‘wix-data’;

// …

wixData.get(“myCollection”, “00001”)
.then( (results) => {
let item = results; //see item below
} )
.catch( (err) => {
let errorMsg = err;
} );

/* item is:
*

  • {
  • “_id”: “00001”,
  • “_owner”: “ffdkj9c2-df8g-f9ke-lk98-4kjhfr89keedb”,
  • “_createdDate”: “2017-05-24T12:33:18.938Z”,
  • “_updatedDate”: “2017-05-24T12:33:18.938Z”,
  • “title”: “Mr.”,
  • “first_name”: “John”,
  • “last_name”: “Doe”
  • }
