How to put footer text on the same line as page number

[KariNabor]

I am trying to generate a footer, I want to put the page number on the same line as the rest of the footer content, but it makes a line break, that is, it puts the number and in the next line the rest. Someone could help me?

`var headerHTMLString = event.header;
var footerHTMLString = '';

var footerContent = event.footer;
var showFooter = false;
var num_page = false;

if(event.number_page == 1){
  num_page = true;
  showFooter = true;
}

if(footerContent !==""){
  footerHTMLString = '<div style="font-size: 7px; display: flex; justify-content: space-between;">';
  if (event.number_page == 1) {
    var no_page = '<span style="text-align: right; flex: 1;display: inline-block;"></span>';
    footerHTMLString = footerHTMLString + no_page + footerContent;
  }
  else{
    footerHTMLString = footerHTMLString + footerContent;
  }
  
  footerHTMLString = footerHTMLString + '</div>';
  showFooter = true;
}

const fileBuffer = await HTMLtoDOCX(htmlString, headerHTMLString, {
table: { row: { cantSplit: true } },
footer: showFooter,
header: true,
pageNumber: num_page}, footerHTMLString );`   

It is my code.
I understand that to display the page number, the library recognizes the space for it, which is the "no_page" string.
Thank you!
