MS-Access - MailMerge specific record from a form

Question

I am creating an Access 2019 database for small family business (dog breeding) so I setup some tables containing all details on the dogs and the owners. Just to give an idea (simplistic description of the situation):

Dogs
    Name
    Birth
    Microchip
    Etc… 

Owners
    Name
    Address
    Etc…

I was now trying to create a "Contract composer" for when we sell the dogs. So I made a new table "Contract" and a related form

Contract
    Seller ->linked to Owners table
    Buyer ->linked to Owners table
    Dog ->linked to Dogs table
    Price

And made a query to pull all relevant information from the related tables so that I can have

ContractQuery
    Seller!Name
    Seller!Address
    Buyer!Name
    Buyer!Address
    Dog!Name
    Dog!Birthdate
    Dog!Microchip
    Contract!Price

Everything so far is working perfectly fine. Now I need to convert the ContractQuery fields in a form of "human readable" contract. I think the best way to do so is the MailMerge to a specific Word document, and I've already setup one. My problem is: how can I set a button into the Contract form so that the "contract.doc" is populated with the specific record I'm seeing now in the form? I had made some researches and the most relevant information I've found is this https://www.access-programmers.co.uk/forums/threads/run-mail-merge-from-vba.158126/ and this https://www.tek-tips.com/faqs.cfm?fid=3237 But they are related to old MS-Access so when I tried to apply it I had errors all around. Unluckily my VBA knowledge is far from being proficient and I was not able to make it work. Can anyone help me, or address me to a solution? Thanks in advance for any advice

OK I got it working thanks to Kostas K, pointing me in the fight direction. This is my final code, it might need some cleanup and tweaking (for example, the loop within the resulst is now redundant as I only have one result), but it is working:)

The solution is based on this post, should anyone need please have a look at it as reference for the template docx etc
