Can I download the 2018 version of indesign?

[Leah5C3D]

I'm a student in my final year of a photography degree. I need indesign to complete a project due end of January 2021. I am using an old apple MacBook Pro I got cheap off Wowcher. I am NOT tech savvy... i have been using photoshop and a number of other applications on the 2018 versions.
Because my Mac is old and does not support the new iOS update I cannot download any newer versions of the apps.
Is there a way I can download the 2018 version of indesign? I have done everything google has suggested... no progress.

iOS is the operating system for iPhones and iPads.

Which OS version do you have on your old Mac (click on the Apple logo, top left, and select About This Mac)?

You can download a trial version of InDesign 2019 to test it on your Mac.
