I have imported a few assets from Dialogue System Extras.
I downloaded and imported 'Visual Novel Framework' and 'Menu Framework for the Dialogue System 2.x', but it seems that these two are conflicting. I keep encountering a CS0246 error.
I have tried reimporting them multiple times, but the issue persists. Could you please advise me on how to resolve this?
Please help me

(For reference, I migrated from Unity 6 LTS to Unity 2022.3 LTS. It seems that Unity 6 still has a lot of issues.)
Could it be due to a namespace conflict? Would it be difficult to use them together...?
