Get a component from another screen

Hi team,

Is there any possibility to get transactionsTable.getSelected() from the ExtMainScreen?

 AppMenu.MenuItem subitem = mainMenu.createMenuItem("myMenu", "myMenu", null, menuItem -> {
//transactionTable.getSelected
 });

where transactionTable is @LookupComponent, part of TransactionBrowse class.

Basically I want to move a button action from Transaction Browse to the Main Menu.

Best Regards,
