Bluetooth Headphone Not Working with Telegram Calls

Samsung TAB S9 ultra

I am experiencing an issue with my Bluetooth headphones when using Telegram for calls.
My Bluetooth headphones work perfectly for listening to media on Telegram and other apps.
I can use the microphone on my Bluetooth headphones to record audio messages in Telegram without any issues.
However, when I make or receive a call on Telegram, the audio switches to the speaker and microphone of my device (tablet).
I am unable to switch to "Bluetooth mode" during the call.

Bluetooth headphones work fine for media and voice recording in Telegram.
Issue is specific to Telegram calls.
I got that only on my tab, not on other phone or computer
