Niche change?

I have been a life coach for almost 7 years. I started out doing general coaching then focused on mompreneurs and finally settled on Helping Highly Sensitive People and Empaths going from Surviving to Thriving.

I have been working in this niche for 3 plus years and started a podcast last year. The last few months I am no longer getting any interest in clarity sessions.

After working on narrowing my niche I came up with the following options. How do I know if the niche is too broad and/or there is a need for this?

Empathic Leaders (helping empathic leaders move from blocked/paralyzed/burnt out stepping into their power and aligned path)
1st/2nd generation Immigrants/POC step into their Purposeful Leadership
