The A1458 is an iPad4.
Update support for you iPad4 ended September 2017. The final iOS releases for this model were iOS 10.3.3 (WiFi Only models) and iOS 10.3.4 (WiFi & Cellular).
iPad4 cannot be updated to any later major version of iOS as it lacks hardware needed to run more recent versions. The 32-bit platform upon which the iPad4 is based is technically obsolete; newer versions of the Operating System are designed to run on 64-bit system architecture and CPU hardware - that the iPad4 doesn’t have. It’s not possible to run 64-bit code on a 32-bit system.
Most App Developers have since dropped support for 32-bit devices (i.e., iOS versions preceding iOS11/12/13) - and have withdrawn older versions of their Apps from the Apple App Store. Withdrawal of Apps supporting older models of iPad is making their utility and usefulness significantly more limited. Once compatible versions Apps are withdrawn, you’ll not be able (re)download or (re)install them.
If Apps that you need to use now have higher minimum iOS-version requirements than your iPad is able to support, your only option is to replace your iPad with newer model. Of current models, even the budget-conscious iPad8 support current iPadOS 14 - and have hardware specifications and capabilities that vastly outperform the very old iPad4.
Whilst clearly not the news that you were hoping to learn, I hope this explanation proves to be helpful - if only in clearly stating the limitations of your iPad4 and your available options.
