Yes, you will need a converter as there are no microphones that have a micro-usb connection by default that would work with your device.
This is an inexpensive, but good quality converter for your tablet: https://www.amazon.com/Female-Headset-Adapter-Active-Microphone/dp/B07LB5P1GB/ref=sr_1_4?dchild=1&keywords=micro+usb+microphone&qid=1625781193&sr=8-4#customerReviews
You can connect any wired microphone to this adapter. I would recommend this one as it is of high sound quality and will last you a long time: https://www.amazon.com/PoP-voice-Professional-Microphone-Omnidirectional/dp/B016C4ZG74/ref=sr_1_8?crid=3QR8U21V72MGA&dchild=1&keywords=lavalier+microphone&qid=1625781333&sprefix=lavalier+%2Caps%2C192&sr=8-8#customerReviews
