Help Needed: Unable to Link eVisa to UKVI Account

I recently opened a UKVI account to link my eVisa to it, as I understand it's no longer necessary to wait for an invite from the Home Office for this step. However, when I log into my account, all I see is the message: "You have no recent applications."

I have already completed my visa application, arrived in UK, collected my BRP, and I expected it to show up here so I could link the eVisa. Has anyone else faced this issue? Is there something I’m missing, or do I need to follow a different process?

I am really stressed and anxious. Any help or advice would be greatly appreciated. Thanks!

Update: I was able to fix it using the YouTube link I have posted in comment
