I got an idea that might solve the right click issue. How about doing something similar to the context menu that appears in Trap Quest whenever you interact with something?
Like there's a crate, you touch the crate and a context menu with the hand hand symbol to open it and the magnifying glass to search the create (there's a third symbol to look at the create too).
A system similar to that could solve the issue, but it would also make the gameplay on pc one click slower, so it would need to be a toggleable option 🤔
