I installed Polylang on my site to translate it from Hebrew to English.

I installed Polylang on my site to translate it from Hebrew to English.
But during the initial configuration I mistakenly clicked on English as the first language when Hebrew should be the first language.
I can add Hebrew as an additional language but there is no way I can make Hebrew the default language!
I tried uninstalling the plugin and reinstalling but it seems that the data was saved in the database.
How can I make Hebrew the default language?
If necessary, I will enter the data base to delete the figure from the table, but I cannot find a new table in the data base.
I would appreciate guidance
