Appearing Bangla/Bengali text in Zoom Whiteboard

[Rabbani83]

Hi,

Can anybody help my writing Bangla text in the whiteboard? Thank you in advance. 

I am using a standard windows laptop. I can type Bangla and it appears nicely in the chatbox, no problem. However, when I am typing in the TEXT BOX in Zoom whiteboard, the Bangla/Bengali text is appearing nicely while the cursor is in the text box. As soon as I am clicking outside the text box, the English text is there, but the Bangla text is becoming either boxes or disappearing completely depending on the different fonts from the zoom'z given list of fonts. By the way, I used Avro Keyboard (National Jatiya) developped by OmicronLab. 

Any help will be highly appreciated.
