Why isn't my website 'Petnomical' showing up on Google?

Hi it has been a couple days since i purchased my domain and finishing my website. When I write my websites name it does not appear on Google? i.e when I search ‘Petnomical’

This is the link to my store - https://petnomical.com/

I was looking to submit my XML sitemap to Google Search Console, however, I was getting confused with the “verifying” my website process. If someone can clarify how to do this as well that would be great.

  1. Ensure your website is accessible: Double-check that your website is accessible to search engines. Sometimes, during development, websites may accidentally have a “noindex” tag or be blocked from search engine crawling. To verify this, check your website’s robots.txt file and remove any “noindex” directives.

  2. Submit your sitemap to Google Search Console: Submitting your XML sitemap to Google Search Console can help search engines discover and index your web pages more efficiently. To do this:

    a. Sign in to your Google Search Console account (create one if you haven’t already).

    b. Add your website property by clicking on the “Add a property” button and following the instructions.

    c. Once your website property is added, select it from the property list and navigate to the “Sitemaps” section.

    d. Click on the “Add/Test Sitemap” button and enter the URL of your XML sitemap. For example, it might be “https://petnomical.com/sitemap.xml”.

I looked at my robots.txt file and it says ‘disallow’ for every search engine (see screenshot). I am pretty sure this is the problem and I need to change this. I have created a robots.txt file in my themes code (see screenshot) although I am unsure what to edit to allow search engines to index my site.

Do you know what code I need to add/edit? (see screenshots)
