Thunkable free version limits

hello,
I can’t access invisible components, which made me think - problem is that I’m using Thunkable free plan. Am I correct?

No. If you’re using the Drag & Drop interface which is the default for new projects, everything is in the sidebar on the Blocks tab. You’re probably reading/watching outdated information. What are you trying to find?

Im trying to find text-to-speech component

Thanks
