MS SQL How to access the database by restoring from a backup?

Question

JavaScript

I was given a database backup in .bak format and restored it using Microsoft SQL Server Management Studio to a local SQL Server. When creating a connection in VS, there is no restored base. I understand that you need to reconfigure users and privileges for the database, but I'm not strong in SQL Server, at all.

Regular expressions are not needed here: UPD. It turns out that the author of the question from the first time was not able to tell what he needed. Taken from the comments:
Oh how. Well, I, in turn, will continue to insist on the uselessness of regular expressions. We create an element, put a string into it, look for the necessary elements, get their markup:

const div = document.createElement('div');
div.innerHTML = str;
const imgsStr = [...div.querySelectorAll('img[src*="/test/"]')].map(n => n.outerHTML).join('');

or

const imgsStr = Array.from(
  new DOMParser().parseFromString(str, 'text/html').querySelectorAll('img[src*="/test/"]'),
  n => n.outerHTML
).join('');

UPD. No, it didn't work the second time either. More details have surfaced:
Delete, so delete:

const div = document.createElement('div');
div.innerHTML = str;
div.querySelectorAll('img[src*="/test/"]').forEach(n => n.remove());
str = div.innerHTML;

or

const d = new DOMParser().parseFromString(str, 'text/html');
d.querySelectorAll('img[src*="/test/"]').forEach(n => n.remove());
str = d.body.innerHTML;
