Hi Everyone,
I'm trying to implement tracking sales pipeline history, and showing under the opportunity as a new tab as outlined in these community posts.
Track Opportunity Sales Stage History - Microsoft Dynamics 365 Community
Track Opportunity Pipeline Stage Change - Dynamics 365 Sales Forum Community Forum
I have followed the instructions to the letter following Leah Ju and dian74, but I must be missing one vital part of getting the new entity form to show in my Opportunity form.
The closest I can get is the following.

I know my process works, when I click on one of the records in the above Opp view I get the form I want to see inside my new entity (Sales Stage History)
This tracks the movement between the stages correctly I believe.

Where I am stuck, is can I display the new entity form (Sales Stage History) inside my Opportunity form? Or is this not how it works?
I've linked all fields correctly I believe, and have 1:N relationships as outlined by Leah Ju in the related post.
When I am inside my Opportunity Main Form, and I have created a new column to house the fields from my new entity, the only field that I can import is my lookup field back to that entity.
This gives me only the name only, when I click on it it takes me to the last record in my new entity form.

Any advice out there for me to try, am I missing a vital key step that is not outlined in the video that dian74 had kindly shared?
Or because all my fields to track sales status are inside another entity, there is no way I can show these fields in my opportunity form directly?
Many thanks in advance everyone,
:) Sean
