IMO, when facing a problem or technology you don't know about. One should clearly articulate to the Manager or BE that the tech is new to you and It will take you x amount of time, this will ensure that stand-ups are less challenging. Second, breaking the problem into smaller problems and then making subtasks out of them is one other thing that can help, you feel you are making progress. 

Third I think, with chatGpt and GitHub Copilot you might be able to use it as a coding partner to learn about new tech and at least get some boilerplate code out and then build on that to solve a problem. Because you or the company expect that you will know RN as well as other front end stuff as well as a specialist is hurting you and the team.
