pca_components not forwarded to pca function when calling add_dimred with umap

[DriessenA]

I get an error when calling dataset <- add_dimred(dataset, dyndimred::dimred_umap, pca_components=NULL)

My dataset is 70.000 x 23 and I want to perform UMAP. However, when running UMAP it first runs PCA with a default number of components of 50. As I only have 23 features I get the error:
Error in (function (A, nv = 5, nu = nv, maxit = 1000, work = nv + 7, reorth = TRUE, : max(nu, nv) must be strictly less than min(nrow(A), ncol(A))

I tried setting the pca_components to other values or to NULL (as the function dimred checks if pca_components !is.null(pca_components) before running PCA. However, the given argument pca_components is never included when internally calling dimred(expression)

Also tried

dataset <- add_dimred(dataset, dyndimred::dimred_umap, pca_components=10)
dataset <- add_dimred(dataset, dyndimred::dimred_umap)

Also, when not running PCA, the umap doesn't work with a sparse matrix
