Right now, focus blocks keep being added to my personal Google account.

The only way to change which account the focus block is created in is to create an event (which will automatically be added to my personal calendar) and then switch it to my work calendar account. After that, new focus blocks will be created in my work calendar account.

Unfortunately, refreshing ClickUp resets this setting, and new events or focus blocks are again created in the personal calendar account. Therefore, the above process must be repeated every time.
