As I want to divide my dataset into four categories, are there any suggestions about how to run a multigroup analysis, by using SmartPLS 3, in order to compare the path coefficients of the 4 groups?
Basically, conduct a pairwise comparison across multiple groups and use a multiple-comparison correction (e.g., Bonferroni or Sidak correction). We provide some insights on the PLS-SEM multigroup analysis (MGA) for more than two groups in this book: Book Advanced Issues in Partial Least Squares Structural Equation Modeling

Dear Isuru Koswatte , a couple of years ago, we created a video on MGA, which is available on the SmartPLS YouTube channel: https://www.youtube.com/channel/UCW4GA7B4zbf-ZsCgSDLuo1Q/videos
