How to make custom texts in jsPDF?

I am using jsPDF and I have this text:

const text = 'Nisi nobis quae minus explicabo consequatur dolores blanditiis.'

By doing this:

doc.setFontSize(9);
doc.text(20,20, text);

I get like this:

Nisi nobis quae minus explicabo consequatur dolores blanditiis.

But I want it to come out like this:

Nisi nobis quae minus explicabo consequatur dolores blanditiis. // the last word with underlining

How do i do it?
