How to export and import components from other .ts file

Hey guys. I am attempting to develop a plugin featuring multiple individual menus. I have noticed that incorporating all functions into a single code.ts file makes it rather difficult to manage. Apparently, Figma does not permit each plugin menu to possess its own *.ts file. Therefore, my resolution was to write each menu into separate .ts files and subsequently, export them, with the aim of importing them into the primary code.ts file. Unfortunately, this original plan of mine does not seem to be functioning as expected. Does anyone have a solution for this issue?
