How to change cell values? - google-apps-script

Question

I'm using Google app script for sheets and I'm new to it.
I have a column with number and a hyperlink in each cell (each link and number is different).
I want to get the link then make an API request which will return a number which will replace that original number for each cell.
At the moment here is my function:
function getLinkUrls() {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getRange("B2:B");
var values = range.getRichTextValues();
for (var i = 0; i < values.length; i++) {
for (var j = 0; j < values[i].length; j++) {
if (values[i][j].getLinkUrl() !== null) {
const val = values[i][j],
url = val.getLinkUrl(),
path = url.split('/')[3];
var response = UrlFetchApp.fetch(`https://decapi.me/twitch/followcount/${path}`),
f = response.getContentText();
}
}
}
}
I want to replace each cell now with f but I'm unsure how.
Table:
Column B should always have hyperlink

I have successful replace the hyperlink with the follower count, you may try if working on your side also, since I did not use getrichtext but getvalue directly:
function getLinkUrls1() {
var sheet = SpreadsheetApp.getActiveSheet();
for (var i = 2; i <= sheet.getLastRow(); i++) {
var url = sheet.getRange(i,2).getRichTextValue().getLinkUrl();
if (url){
var path = url.split('/')[3];
var response = UrlFetchApp.fetch(`https://decapi.me/twitch/followcount/${path}`),
f = response.getContentText();
sheet.getRange(i,2).setRichTextValue(SpreadsheetApp.newRichTextValue()
.setText(f).build());
}
}
}
This is my sample data:
