Url format issues for SEO

Hi
On our wordpress member site, we have public site content we want indexed by SEO and some of the pages are not being seen for SEO purposes at present. Looking for some help. We have a section on our public site at https://www.gleanr.com.au/plant-wizard where a user can search for a plant. We want all the searchable plants to be indexed for SEO and we are putting metatags on all of them them, this is an example: https://www.gleanr.com.au/plant-detail-public/Amaranth . We have 140 plant pages sitting ready to be accessed from the public site and at present these pages in the url format shown for Amaranth are not being seen by Google or Bing. We have metadata tags for the pages in our plant database and the Amaranth one has the tags. So my question, in having used Yoast for many years and loving the product, is how can we get these dynamic pages be viewable for SEO. For Google, do I need to put each of the plant pages onto the sitemap or is there another solution? Thanks
