Latex - How can I use minipage inside longtable? - latex

Question

I have a table that I would like to split over pages, but I can't seem to figure out how I can do it with my current lay-out or commands that I use.
At this time, I used landscape and minipage so that it would fit on one page:
\documentclass[11pt]{article}
\usepackage{pdflscape}
\usepackage{longtable}
\usepackage{lipsum}
\usepackage{bm}
\usepackage{makecell}
\begin{document}
\begin{landscape}
\centering
\begin{table}[!htb]
\caption{\label{CH2_tab:P80L} Empirical power from the simulation study with the indicators having an overall reliability of 80\% and a linear relationship with the latent variable. The highest power per setting is indicated in bold.}

However, I would like to split this table nicely over multiple pages (and thus by using e.g. longtable), in such way that on one page, I have the results for the N(0,1) and Laplace distribution (side by side), and then on the second page the t_5 and Exp distribution (side by side), i.e. split each table over 2 pages, but have 2 tables side by side by using minipage inside long table.
I know I could converge them and just make one large table and then use long table, however, I would really like not to rewrite the code (since I have 10 more tables like this). Does someone know how I could do this? I tried several ways, but none of them produce the result I am looking for.
Thank you for all your feedback!
