Enter key is missing in Samsung keyboard while using Google calendar

[yyaa]

Whenever I use Google calendar, the Enter key is replaced with Done. I wonder how can I insert a new line?

I'm using Samsung keyboard on Samsung Galaxy S22.

Done appears for Add title. If number of characters exceed the length then it continues on second line.

Enter appears for Add details.

Conclusion: the title cannot be split into 2 lines.
