How to authenticate user (the host of meeting) through iframe, using web app credentials

Hi,

We have implemented the board on our web app using iframe integration, but when a host wants to share the video or start video chat he/she needs to log in first through miro.com.
We want to authenticate the user without going to miro.com, is there any way to set authentication through iframe or any API calls?

Thanks in advance!

regards,

Kundan
