Notion Integration problem

Hello,

I connected my Notion database with Tablesome and wanted to use it to integrate my Elementor form submissions into Notion. However, when I try to select the action, columns do not show up and the entire screen gets frozen for some reason, I cannot anything other than Update Table button. After even clicking on it, when I try to open the table once more to check it again, nothing appears. Just the title and the Update Table button, nothing else.

I really need this integration and I think this is some sort of a bug. Can you help me with this?

Thanks a lot!
