Responsive Event Scheduler for WordPress plugin alternative

I’m using an event plugin that I bought on Envato called Responsive Event Scheduler for WordPress in one of my WP sites. This plugin is no longer available and its last update was in 2019:

Fearing that in time this plugin will cause problems in future WP and PHP versions, I’m thinking of moving to an alternative. I’m looking for a new plugin that display events as close as possible to the old plugin. Here is a demo of the old plugin:

Does anyone here used this plugin? Any ideas for a similar alternative plugin?

Thanks in advance
