Here you is the documentation for all modules https://wpeden.com/minimax-wordpress-page-layout-builder-plugin/docs/
And we do have a demo site to check the features of plugins before purchase. You can’t expect it to do more than what it is.
We will be happy to consider a refund, if you are unable to get the plugin to install properly on your website or if the plugin fails to perform the basic functions as designed and you have worked with the product support team to try to resolve these issues.
But that’s not the case here.
Let us know if you need any help in setting up the plugin or any support question. PLease use this forum for MiniMax queries https://wpeden.com/forums/forum/plugin-support/minimax/
