Mike and stream recording

I am teaching music online through a platform named Doozzoo. It has a feature where you can record through the microphone. There is also an audioplayer.

Because I would like to record me playing over a backing track I installed Voicemeeter and Virtual Audio Cable and easy Trumpet, following the excellent Franswah instructions.

Now I can record what is playing through the audio player, or from the microphone, but alas: not together. I guess there must be a way....

I selected the virtual cable as input, and Voicemeeter aux as output.

Now I can record the audiplayer, but not the mike.

Any suggestions?
