Try setting initialDir to content://com.android.externalstorage.documents/document/primary%3AMyFolder%2F
When you choose a dir with SAF Picker you will find tree in place of document.

By clicking on it. (How else?) 
How can I get the selected file uristring ? With OpenDocumentTree block I get the uristring of selected folder, not the uristring of selected file-
I know the folder, I know the filename , is it possible to open it with only one pick ?
It is possible and a work of adding just one line. Its implementation will take few days.
OK, thank you, I realized that using OpenDocumentTree block and clicking as attached you can view the file content.
You can try this beta version:

Can you explain me the difference betwen type and extraMimeTypes ? can I use them for showing my desired file only ?
I mean all filenames starting with P
Then you have to list all files first and check then which of them start with "P".
I need to pick file or folder for opening, after picking I get automatically write/read permissions, why there are permission blocks ? When I need to use them ?
Is there a reason why this is not available in your latest extension version? @vknow360
Sorry, I forgot to add that method.

Firstly, why is the file in the Download folder? Does it have to be downloaded from the cloud? If so, you can download it directly to the App's ASD folder:
However, Download is an Android shared folder, you do not need SAF to access it.
