Website re-verification requested by google console

Hello! I need help with a problem I am having and started with google ads. All my search ads were blocked do too a large volume of Soft 404 caused by changes in Shopify urls. From that, google ads stopped my campaigns. And since my google ranking decreased dramatically, they also requested I re-verify the website ownership. Under google my business I had an old page developed using google my site app but I wanted to change to my ecommerce domain. Google did not allow that to happen. Under google console, google requests that I add a new TXT verification configuration under the DNS table I have today hosted outside of google. I am afraid that this new google website verification will make me loose my current ecommerce url because it seems Google is pushing me to migrate to Google Cloud services which I do not want to. My domain is hosted by Shopify. How would I know if this new domain address verification is my ecommerce? And if this is not requesting a change in who hosts my domain? And if my ecommerce url is being preserved and not being changed to the google hosted page I had to create under Google my business? Who can help?
