Internal server error 500 Object.hasOwn is not a function

[cladveloper]

Hi developers, my website does not work in certain browsers running an old version of javascript. The problem comes from a function of this module (nuxt-alt/auth). What I can do?

Test in production mode with iPhone 7 with ios 14.4.2

500
Object.hasOwn is not a function (In 'Object.hasOwn(e.meta, "auth)', 'Object.hasOwn is undefined'

Thanks a lot
