Phone Call Erro

Hello. I have a small problem with my application. I have the following block for calls.
blocks (1)
If the user denies permission and opens the page again, the application stops working and is closed. If the user accepts the calling permission, no problem occurs.

I appreciate any help.

PS: I did a new test and when the permission is denied, any page that is accessed, the application stops working and is closed.

I think this might be a bug however possibly you could some of these blocks as a work around?


Thanks for the answer. It seems that if you add the call component, even if there is no block requesting calls, the application will ask for permission and the bug happens anyway. I chose to use the following block, it seems to work well.
