How to choose a plugin for Google Chrome to auto-replace the html code of a page?

Question

Google Chrome

Friends, hello everyone!
Let me explain the situation:
At work I work with clients in web CRM. The client card has a table that lists all contacts (DM, phones, mail), next to each phone number and mail there is a status (Correct number / mail, not correct, or the status is "Not set"). The fact is that visually the fields and current statuses are merged in the table and at first glance it is not possible to determine the current mail with many fields.
I tried to discuss this issue with the developers, but they are too lazy to change something for one person, and the management considers it inappropriate to set this task for them, since I am the only one who is not satisfied with this state of affairs.
As a result, I came to the conclusion that it makes sense to get some kind of simple browser extension that would automatically analyze the current page and replace / supplement the page's client code with the one that I will write. The result should be the following - when generating the page in the browser, the plugin analyzed the content, found a block that meets the specified conditions and replaced part of the code in it with mine, then I see the page the way I would like to see it.
Actually the question is, tell me a similar extension for Google Chrome? If possible, with documentation in Russian / English.
Thanks in advance!
