For this purpose, you will need to have MetaMask installed.
If you don’t have it installed already, don’t fret. Albeit an easy process, some MetaMask extensions are made by hackers and can be phony and dangerous, breaching your privacy.

3. Then click “Connect”. The RPC will now be connected to your MetaMask wallet
4. The MetaMask extension will pop up again. Click “Approve” as it asks for your permission to allow Metaschool to add the network to your MetaMask wallet
5. Once you have approved, you can either allow Metaschool to automatically switch to the custom network or you can go back to MetaMask dashboard and see your custom network there.
