Is it possible to create a plugin for Google that would copy certain data from the desired pages?

Question

Google Chrome

Hello! Interested in this question:
There is a site with job offers,
What I do, open each offer in a new tab, I find contacts there (usually they are in one block on the page, you can see from the picture) e-mail, phone number, company name and contact face) and copy all this (separately) into a table. I am attaching an example
Is it possible to write a plugin, a browser extension that would collect all this information for me in a table (an example of a table
has one column for emails, the second for the site, the third for the number, the fourth for the company, the fifth for the contact person
And it is desirable that the extension took information from a specific block on the page, because free email search extensions look for them on the entire page, which leads to confusion.
How can all this be done?) If not by yourself, then at least how much the development of such an extension could cost, if possible.
Maybe you can write something in the page code?
