Hello,
Thank you for getting in touch with us.
Was your old domain indexed? Do you wish to transfer the Old doamin rank and indexing data to your new domain. If so, you will need to redirect all URLs from your previous domain to your new domain. To do so, please follow this guide: https://www.stepforth.com/resources/web-marketing-knowledgebase/how-to-redirect-an-old-domain-to-a-new-domain/
If you wish to create your new domain as a new site, please note that newly websites take time before it gets crawled or indexed by Google. It depends on a lot of factors. Your posting frequency + the domain authority are just two of the many factors Google considers when indexing some new URL. Google assigns a crawl budget to your website depending on these factors (especially these two) and that has a direct effect on how soon or how late your content can get indexed.
With that said, if your site is not set to noindex, we have found that barring any issues like copied/DMCA/low-quality content issues – Google usually indexes posts within a week or two. So, we request you to kindly wait.
Google even says that on their official website:

So, you have to be a bit patient and allow it some time. If your website isn’t indexed even after a week, you can place a manual indexing request here:

Finally, it all boils down to the quality of the content, and if your content improves Google’s overall search index.
Please check this article where one of the Google employees mentioned:
“If your site relies on manual index submission for normal content, you need to significantly improve your site. Search console does not fix your site, you need to do that yourself.” – JohnMu
