Sharing a built app

I am a somewhat old very amateur ex maths teacher who attempts a little coding in XOJO. It is usually very simplistic and I usually have to do a lot of research in the documentation to get things to “work” but I very much enjoy it. I have built a few substantial projects and some mini ones.
I have no commercial intentions but would like to share some of my creations with family members. A recent forum post I read talked about distribution issues and that with other posts has always lost me fairly early in the process. I did find an older walk through, but that fell apart as I think interfaces in Xcode have changed.
So I build an app in Mac OS with latest versions of Mac OS and xojo. It works flawlessly. For the sake of argument assume it is a small project using a SQLite database that details some family history around items in my house.
I don’t want to pay additional apple licences but I would like a family member to have this package on her MacBook. I assume security over an unsigned app on another machine will be an issue.
Do I have options? I assume yes - I could get her to install XOJO and use my source code to build it on her machine seems the wrong approach!
Is there a real idiots guide to a step by step process to make this happen elegantly (or is there even a need for this as I cannot be the only person looking to do this in my very amateur way as opposed to a professional providing apps for a client).

If it’s a family member you’re trying to share with you could use an app like Sentinel on their machine to unquarantine and self-sign the application (no certificate or Apple fees required) so that the application will launch.

You will need to drag and drop your unsigned application onto Sentinel on the destination machine, so this is not a system that can be used to distribute your application to the general public.

To download the built version click on “Releases” on the sidebar.

I can commend @Tim_Parnell 's suggestion - I have a user doing this. In this case my app is signed and notarised, but he wants to use it in a non-standard way and Sentinel solves that for him.

Thank you for this - I will try it in a couple of weeks when the machine is to hand.

Thank you
