How to jump to a specific tab when startActivity android is called?

Question

Android

I have two lists of messages in the application, incoming and outgoing which are placed on two tabs, then when I select one of the messages, I go to the activity where the message is displayed. This activity has a toolbar at the bottom where the back button is located, but I can currently go to the first tab, but I need something like we opened a message from the inbox list and then when we return to the previous message list, go to the inbox list, and so - same to do with outgoing. Can somehow pass position to an activity that has a recyclerview and slidingtabs? I now have such a listener for the choice of tabs:

tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                viewPager.setCurrentItem(tab.getPosition());
                /*String position = String.valueOf(tab.getPosition());
                Toast.makeText(SecondScreen.this,position,Toast.LENGTH_LONG).show();*/
            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab) {

            }

            @Override
            public void onTabReselected(TabLayout.Tab tab) {

            }
        });

I'm thinking where to pass position? after all, in fact, if viewPager.setCurrentItem(tab.getPosition());
I insert into this piece of code, then I will only select the tab that comes with the intent, and on my own when the application starts, it will not be known which tab to select. Perhaps I explained very confusingly, but I hope for help and advice.

when you call an activity with tabs from the screen with a message - pass the position to it via intent.putExtra("position", index);
and inside the activity - getIntent.getIntExtra("position", defIndex); And instead of defIndex - the index of the tab to open if nothing came (for example, when you get to the screen with tabs from other places)
