How to pass variables to SuiteQL

Question

I am trying to pass parameters from the current record to an embedded Suitelet though cannot find the right syntax to do this anywhere

My starting point was using the Suitelet code here: https://timdietrich.me/blog/netsuite-suiteql-query-results-custom-tabs/

The result from my modified version is per this screencap

When the page loads, the SuiteQL record field is populated using the current record's internal Id.

What I want to do is pass this value as a variable to the embedded SuiteQL Suitelet so that the search results are only in relation to the stated record (in this case, the record with the internal id=24486).

Is this actually possible?

If it is possible, how do I pass this value to the SQL query parameters?
